                           WESTERN DIGITAL CORPORATION

        We design, develop, manufacture and market a broad line of rigid
magnetic disk drives, often referred to as hard drives, for use in desktop
personal computers. A hard drive is an electromechanical device used for
information storage and retrieval, incorporating one or more rotating disks on
which data is recorded, stored and read magnetically. We market our products
worldwide to computer manufacturers, distributors, resellers and retailers. Our
goal is to become a leading manufacturer of hard drives in the hard drive
markets in which we compete.

        In February 1999, we acquired a startup company called Crag
Technologies, Inc., which we renamed Connex, Inc. after the acquisition. Connex
is focused on developing storage solutions for local area network servers. In
January 2000, we announced that we will exit the enterprise hard drive business
and shift our strategic focus and resources in the enterprise space to
Internet-related data content management systems and management software. We
plan to leverage our experience with hard drives to develop these additional
storage systems and components in order to enhance our business model.

        We are incorporated in the State of Delaware. Our principal executive
offices are located at 8105 Irvine Center Drive, Irvine, California 92618 and
our telephone number is (949) 932-5000.

                                  RISK FACTORS

        An investment in our common stock involves a high degree of risk. You
should carefully consider the following risk factors primarily related to our
common stock offered by this prospectus and to our business and operations. You
should also carefully consider the other information in this prospectus and in
the documents incorporated by reference. Some of these factors have affected our
financial condition or operating results in the past or are currently affecting
us. All of these factors could affect our future financial condition or
operating results. If any of the following risks actually occurs, our business,
financial condition or results of operations could be harmed. If that happens,
the trading price of our common stock could decline, and you may lose all or
part of your investment.

        Within this prospectus, we sometimes refer to years without specifying
the month or day of that year. In all such cases, unless we specifically refer
to a calendar year, the reference is to our fiscal year ended on or about June
30 of such year.

RISK FACTORS RELATED TO THE HARD DRIVE INDUSTRY IN WHICH WE OPERATE

Our operating results depend on our being among the first-to-market and
first-to-volume with our new products.

     To achieve consistent success with computer manufacturer customers we must
be an early provider of next generation hard drives featuring leading technology
and high quality. If we fail to:

     -  consistently maintain and improve our time-to-market performance with
        our new products

     -  produce these products in sufficient volume within our rapid product
        cycle

     -  qualify these products with key customers on a timely basis by meeting
        our customer's performance and quality specifications, or

     -  achieve acceptable manufacturing yields and costs with these products

then our market share would be adversely affected, which would harm our
operating results.


                                       2

Short product life cycles make it difficult to recover the cost of development.

     Over the past two years hard drive areal density (the gigabytes of storage
per disk) has increased at a much more rapid pace than previously, and we expect
this trend to continue. Higher areal densities mean that fewer heads and disks
are required to achieve a given drive capacity. This has significantly shortened
product life cycles, since each generation of drives is more cost effective than
the previous one. Shorter product cycles make it more difficult to recover the
cost of product development.

Short product life cycles force us to continually qualify new products with our
customers.

     Due to short product life cycles, we must regularly engage in new product
qualification with our customers. To be considered for qualification we must be
among the leaders in time-to-market with our new products. Once a product is
accepted for qualification testing, any failure or delay in the qualification
process can result in our losing sales to that customer until the next
generation of products is introduced. The effect of missing a product
qualification opportunity is magnified by the limited number of high volume
computer manufacturers most of which continue to consolidate their share of the
PC market. These risks are magnified because we expect cost improvements and
competitive pressures to result in declining sales and gross margins on our
current generation products.

Our average selling prices and our revenue are declining.

     We expect that our average selling prices for hard disk drives will
continue to decline. Rapid increases in areal density mean that the average
drive we sell has fewer heads and disks, and is therefore lower cost. Because of
the competitiveness of the hard drive industry, lower costs generally mean lower
prices. This is true even for those products that are competitive and introduced
into the market in a timely manner. Our average selling prices decline even
further when competitors lower prices to absorb excess capacity, liquidate
excess inventories, restructure or attempt to gain market share.

Unexpected technology advances in the hard drive industry could harm our
competitive position.

     If one of our competitors were able to implement a significant advance in
head or disk drive technology that enables a step-change increase in areal
density allowing greater storage of data on a disk, it would harm our operating
results.

     Advances in magnetic, optical, semiconductor or other data storage
technologies could result in competitive products that have better performance
or lower cost per unit of capacity than our products. Some of our competitors
are developing hybrid storage devices that combine magnetic and optical
technologies, but we have decided not to pursue this technology at this time. If
these products prove to be superior in performance or cost per unit of capacity,
we could be at a competitive disadvantage to the companies offering those
products.

The hard drive industry is highly competitive and characterized by rapid shifts
in market share among the major competitors.

     The price of hard drives has fallen over time due to increases in supply,
cost reductions, technological advances and price reductions by competitors
seeking to liquidate excess inventories or gain market share. In addition, rapid
technological changes often reduce the volume and profitability of sales of
existing products and increase the risk of inventory obsolescence. These
factors, taken together, result in significant and rapid shifts in market share
among the industry's major participants. For example, during 1997, we
significantly increased our share of the desktop market, but these gains were
lost during 1998 and 1999. If our market share erodes further, it would likely
harm our operating results.

Our prices and margins are subject to declines due to unpredictable end-user
demand and oversupply of hard disk drives.

     Demand for our hard drives depends on the demand for computer systems
manufactured by our customers and on storage upgrades to existing systems. The
demand for computer systems has been volatile in the past and often


                                       3
<PAGE>   5
has had an exaggerated effect on the demand for hard drives in any given period.
As a result, the hard drive market tends to experience periods of excess
capacity which typically lead to intense price competition. If intense price
competition occurs, we may be forced to lower prices sooner and more than
expected and transition to new products sooner than expected. For example, in
the second half of 1998 and throughout 1999, as a result of excess inventory in
the desktop hard drive market, aggressive pricing and corresponding margin
reductions materially adversely affected our operating results. We experienced
similar conditions in the high-end hard drive market during most of 1998 and
1999.

Changes in the markets for hard drives require us to develop new products.

     Over the past few years the consumer market for desktop computers has
shifted significantly towards lower priced systems, especially those systems
priced below $1,000. If we do not develop lower cost hard drives that can
successfully compete in this market, our market share will likely fall, which
could harm our operating results.

     Furthermore, the PC market is fragmenting into a variety of computing
devices and products. Some of these products, such as internet appliances, may
not contain a hard drive. On the other hand, many industry analysts expect, as
do we, that as broadcasting and communications are increasingly converted to
digital technology from the older, analog technology, the technology of
computers and consumer electronics and communication devices will converge, and
hard drives will be found in many consumer products other than computers. While
we are investing development resources in designing hard drive products for new
audio-visual applications, it is too early to assess the impact of these new
applications on future demand for hard drive products.

We depend on our key personnel.

     Our success depends upon the continued contributions of our key employees,
many of whom would be extremely difficult to replace. Worldwide competition for
skilled employees in the hard drive industry is intense. We have lost a number
of experienced hard drive engineers over the past year as a result of the loss
of retention value of our employee stock options (because of the decrease in
price of our common stock) and aggressive recruiting of our employees. If we are
unable to retain our existing employees or to hire and integrate new employees,
our operating results would likely be harmed.

RISK FACTORS RELATING TO WESTERN DIGITAL PARTICULARLY

Loss of market share with a key customer could harm our operating results.

     A majority of our revenue comes from a few customers. For example, for the
six month period ended December 31, 1999, sales to our top 10 customers
accounted for approximately 62% of revenues. These customers have a wide variety
of suppliers to choose from and therefore can make substantial demands on us.
Even if we successfully qualify a product with a customer, the customer
generally is not obligated to purchase any minimum volume of products from us
and is able to terminate its relationship with us at any time. Our ability to
maintain strong relationships with our principal customers is essential to our
future performance. If we lose a key customer or if any of our key customers
reduce their orders of our products or require us to reduce our prices before we
are able to reduce costs, our operating results would likely be harmed. For
example, this occurred early in the third quarter of 2000 in our enterprise hard
drive business and is one of the factors which led to our decision to exit the
enterprise hard drive business and close our Rochester, Minnesota facility.

Dependence on a limited number of qualified suppliers of components could lead
to delays or increased costs.

     Because we do not manufacture any of the components in our hard drives, an
extended shortage of required components or the failure of key suppliers to
remain in business, adjust to market conditions, or to meet our quality, yield
or production requirements could harm us more severely than our competitors,
some of whom manufacture certain of the components for their hard drives. A
number of the components used by us are available from only a single or limited
number of qualified outside suppliers. If a component is in short supply, or a
supplier fails to qualify or has a quality issue with a component, we may
experience delays or increased costs in obtaining that component. This occurred
in September 1999 when we had to shut down our Caviar product line production
for


                                       4
<PAGE>   6
approximately two weeks as a result of a faulty power driver chip which was
sole-sourced from a third-party supplier.

     To reduce the risk of component shortages, we attempt to provide
significant lead times when buying these components. As a result, we may have to
pay significant cancellation charges to suppliers if we cancel orders, as we did
in 1998 when we accelerated our transition to magnetoresistive recording head
technology, and as we are doing as a result of our decision to exit the
enterprise hard drive business.

     In April 1999, we entered into a three year volume purchase agreement with
Komag under which we will buy a substantial portion of our media components from
Komag. We intend that this strategic relationship will reduce our media
component costs; however, it increases our dependence on Komag as a supplier.
Our future operating results will depend substantially on Komag's ability to
timely qualify its media components in our new development programs and to
supply us with these components in sufficient volume to meet our production
requirements. Any disruption in Komag's ability to manufacture and supply us
with media would likely harm our operating results.

To develop new products we must maintain effective partner relationships with
our strategic component suppliers.

     Under our "virtual vertical integration" business model, we do not
manufacture any of the parts used in our hard drives. As a result, the success
of our products depends on our ability to gain access to and integrate parts
that are "best in class" from reliable component suppliers. To do so we must
effectively manage our relationships with our strategic component suppliers. We
must also effectively integrate different products from a variety of suppliers
and manage difficult scheduling and delivery problems. Failure to gain access to
parts or manage this integration could harm our operating results.

We have only one manufacturing facility, which subjects us to the risk of damage
or loss of the facility.

     Our volume manufacturing operations currently are based in one facility. A
fire, flood, earthquake or other disaster or condition affecting our facility
would almost certainly result in a loss of substantial sales and revenue and
harm our operating results.

Manufacturing our products abroad subjects us to numerous risks.

     We are subject to risks associated with our foreign manufacturing
operations, including:

     -  obtaining requisite United States and foreign governmental permits and
        approvals

     -  currency exchange rate fluctuations or restrictions

     -  political instability and civil unrest

     -  transportation delays or higher freight rates

     -  labor problems

     -  trade restrictions or higher tariffs

     -  exchange, currency and tax controls and reallocations

     -  loss or non-renewal of favorable tax treatment under agreements or
        treaties with foreign tax authorities.

     We attempt to manage the impact of foreign currency exchange rate changes
by, among other things, entering into short-term, forward exchange contracts.
However, those contracts do not cover our full exposure and can be canceled by
the issuer if currency controls are put in place, as occurred in Malaysia during
the first quarter of 1999.


                                       5

Our plan to broaden our business in data and content management, storage and
communication takes us into new markets.

     We have recently entered the storage subsystem market through our Connex
subsidiary. In this market we will be facing the challenges of building volume
and market share in a market which is new to us but which has several
established and well-funded competitors. There is already significant
competition for skilled engineers, both in the hardware and software areas, in
this market. Our success will depend on Connex's ability to develop, introduce
and achieve market acceptance of new products, applications and product
enhancements, and to attract and retain skilled engineers. Additionally, our
competitors in this market have established intellectual property portfolios.
Our success will also depend on our ability to license existing intellectual
property or create new innovations. Moreover, our competitors' established
intellectual property portfolios increase our risk of intellectual property
litigation.

     We are also developing hard drives for the emerging audio-visual market. We
will be facing the challenge of developing products for a market that is still
evolving and subject to rapid changes and shifting consumer preferences. There
are several competitors which have also entered this emerging market, and there
is no assurance that the market for digital storage devices for audio-visual
content will materialize or support all of these competitors.

     We also expect to enter the data warehouse software and services market
through our SageTree subsidiary and are considering other initiatives related to
data and content management, storage and communication. In any of these
initiatives we will be facing the challenge of developing products and services
for markets that are still evolving and which have many current and potential
competitors.

Our reliance on intellectual property and other proprietary information subjects
us to the risk of significant litigation.

     The hard drive industry has been characterized by significant litigation.
This includes litigation relating to patent and other intellectual property
rights, product liability claims and other types of litigation. We are currently
evaluating several notices of alleged patent infringement or notices of patents
from patent holders. We also are a party to several judicial and other
proceedings relating to patent and other intellectual property rights. If we
conclude that a claim of infringement is valid, we may be required to obtain a
license or cross-license or modify our existing technology or design a new
non-infringing technology. Such licenses or design modifications can be
extremely costly. We may also be liable for any past infringement. If there is
an adverse ruling against us in an infringement lawsuit, an injunction could be
issued barring production or sale of any infringing product. It could also
result in a damage award equal to a reasonable royalty or lost profits or, if
there is a finding of willful infringement, treble damages. Any of these results
would likely increase our costs and harm our operating results.

Our reliance on intellectual property and other proprietary information subjects
us to the risk that these key ingredients of our business could be copied by
competitors.

     Our success depends, in significant part, on the proprietary nature of our
technology, including our non-patentable intellectual property such as our
process technology. Despite safeguards, to the extent that a competitor is able
to reproduce or otherwise capitalize on our technology, it may be difficult,
expensive or impossible for us to obtain necessary legal protection. Also, the
laws of some foreign countries may not protect our intellectual property to the
same extent as do the laws of the United States. In addition to patent
protection of intellectual property rights, we consider elements of our product
designs and processes to be proprietary and confidential. We rely upon employee,
consultant and vendor non-disclosure agreements and a system of internal
safeguards to protect our proprietary information. However, we cannot insure
that our registered and unregistered intellectual property rights will not be
challenged or exploited by others in the industry.

Inaccurate projections of demand for our product can cause large fluctuations in
our quarterly results.

     If we do not forecast total quarterly demand accurately, it can have a
material adverse effect on our quarterly results. We typically book and ship a
high percentage of our total quarterly sales in the third month of the quarter,
which makes it difficult for us to match our production plans to customer
demands. In addition, our quarterly


                                       6
<PAGE>   8
projections and results may in the future be subject to significant fluctuations
as a result of a number of other factors including:

     -  the timing of orders from and shipment of products to major customers

     -  our product mix

     -  changes in the prices of our products

     -  manufacturing delays or interruptions

     -  acceptance by customers of competing products in lieu of our products

     -  variations in the cost of components for our products

     -  limited access to components that we obtain from a single or a limited
        number of suppliers, such as Komag

     -  competition and consolidation in the data storage industry

     -  seasonal and other fluctuations in demand for computers often due to
        technological advances.

Rapidly changing market conditions in the hard drive industry make it difficult
to estimate actual results.

     We have made and continue to make a number of estimates and assumptions
relating to our consolidated financial reporting. The rapidly changing market
conditions with which we deal means that actual results may differ significantly
from our estimates and assumptions. Key estimates and assumptions for us
include:

     -  accruals for warranty against product defects

     -  price protection adjustments on products sold to resellers and
        distributors

     -  inventory adjustments for write-down of inventories to fair value

     -  reserves for doubtful accounts

     -  accruals for product returns.

The market price of our common stock is volatile.

     The market price of our common stock has been, and may continue to be,
extremely volatile. Factors such as the following may significantly affect the
market price of our common stock:

     -  actual or anticipated fluctuations in our operating results

     -  announcements of technological innovations by us or our competitors
        which may decrease the volume and profitability of sales of our existing
        products and increase the risk of inventory obsolescence

     -  new products introduced by us or our competitors

     -  periods of severe pricing pressures due to oversupply or price erosion
        resulting from competitive pressures

     -  developments with respect to patents or proprietary rights

     -  conditions and trends in the hard drive industry


                                       7
<PAGE>   9
     -  changes in financial estimates by securities analysts relating
        specifically to us or the hard drive industry in general.

     In addition, the stock market in recent months has experienced extreme
price and volume fluctuations that have particularly affected the stock price of
many high technology companies. These fluctuations are often unrelated to the
operating performance of the companies.

   Securities class action lawsuits are often brought against companies after
periods of volatility in the market price of their securities. A number of such
suits have been filed against us in the past, and any of these litigation
matters could result in substantial costs and a diversion of resources and
management's attention.

We may be unable to raise future capital through debt or equity financing.

   Due to our recent financial performance and the risks described in this
prospectus, in the future we may be unable to maintain adequate financial
resources for capital expenditures, working capital and research and
development. Our current borrowing agreement with our banks terminates no later
than March 31, 2000, and we have agreed that we will not borrow under the
agreement. If we decide to increase or accelerate our capital expenditures or
research and development efforts, or if results of operations do not meet our
expectations, we could require additional debt or equity financing. However, we
cannot insure that additional financing will be available to us or available on
favorable terms. An equity financing could also be dilutive to our existing
stockholders.

Year 2000

   On January 1, 2000, we incurred nominal impact on our products, equipment,
computer systems and applications as a result of the Year 2000 issue. As of
December 31, 1999, systems remediation and integration testing and development
of our contingency plans had been completed. Supplier management is an ongoing
process, and no material impact was felt from lack of supplier readiness at
January 1, 2000. Although we did not experience any material problems related to
the Year 2000 issue, there can be no assurances that problems relating to the
Year 2000 issue will not manifest themselves in the future.

                                 USE OF PROCEEDS

        We will not receive any proceeds from the sale of the shares of common
stock by the selling stockholder.

                               SELLING STOCKHOLDER

        As partial consideration for the settlement of a lawsuit which alleged
infringement by us of several patents, we issued in a private transaction a
warrant to purchase the shares to the selling stockholder who is the holder of
the patents. We issued the warrant on January 10, 2000. As of the date of this
prospectus, the selling stockholder has not exercised the warrant. Upon exercise
of the warrant, the shares of common stock will be issued to the selling
stockholder in a private transaction.

        The selling stockholder may from time to time offer and sell pursuant to
this prospectus up to 250,000 shares of our common stock. The following table
sets forth, as of April 30, 2000, the number of shares of our common stock that
the stockholder beneficially owns. The term "selling stockholder" includes the
holder listed below and its transferees, pledgees, donees or other successors
receiving shares from the holder listed below after the date of this prospectus.
We have prepared this table based upon information furnished to us by or on
behalf of the selling stockholder. Based on information provided to us by the
selling stockholder, the selling stockholder does not beneficially own any
shares of our common stock other than those listed in the table below.

        The selling stockholder does not own more than 1% of our outstanding
common stock. The selling stockholder has not had any material relationship with
us during the past three years.

        The selling stockholder confirmed at the time it acquired the warrant
and will confirm at the time it acquires the shares listed below that the
acquisition of the securities is for investment purposes only and not with a


                                       8

view toward their resale, and acknowledged and will acknowledge the existence of
restrictions under the Securities Act of 1933 as amended on resale applicable to
these securities. This offering relates only to the sale of shares to be held by
the selling stockholder named in the following table. The selling stockholder
may sell, transfer or otherwise dispose of some or all of its shares of our
common stock in transactions exempt from the registration requirements of the
Securities Act.

                              PLAN OF DISTRIBUTION

        The selling stockholder can use this prospectus to sell the shares at
any time while the prospectus is in effect, unless we have notified the selling
stockholder that the prospectus is not then available. The selling stockholder
will determine if, when and how it will sell the shares it owns. Any sales may
occur in one or more of the following types of transactions (including block
transactions):

        -  transactions on the New York Stock Exchange or any other organized
           market where the shares may be traded; or

        -  privately negotiated transactions between the selling stockholder and
           the purchaser; or

        -  transactions effected with or through a broker-dealer acting as
           either agent or principal.

        These transactions may involve transfer of the shares upon exercise or
settlement of put or call options, or delivery of the shares to replace shares
that were previously borrowed from another stockholder or a combination of such
methods. If a broker-dealer is used in the sale of shares, that person may
solicit potential purchasers. The shares may also be transferred as a gift or
pursuant to a pledge, or may be sold to a broker-dealer acting as principal.
These persons may then sell the shares to another person, either directly or
through another broker-dealer, subject to compliance with the requirements of
the Securities Act.

        The price at which sales of the shares occur may be based on market
prices or may be negotiated between the parties, and the consideration may be
cash or another form negotiated between the parties. Broker-dealers acting as
agents or principals may be paid compensation in the form of discounts,
concessions or commissions from the selling stockholder and/or from the
purchasers of the shares, or both. Brokers or dealers may be deemed to be
"underwriters" within the meaning of the Securities Act. Any profits on the
resale of shares by a broker-dealer acting as principal might be deemed to be
underwriting discounts or commissions under the Securities Act. Discounts,
concessions, commissions and similar selling expenses, if any, attributable to
the sale of shares will be borne by the selling stockholder and/or the
purchasers. We have agreed to pay certain of the costs, expenses and fees of
preparing, filing and maintaining this prospectus and the registration statement
of which this prospectus is a part, but we will not receive any proceeds from
the sale of these shares. The selling stockholder may agree to indemnify any
agent, dealer or broker-dealer that participates in transactions involving sales
of the shares if liabilities are imposed on it under the Securities Act.


                                       9
<PAGE>   11

        The selling stockholder has advised us that it has not entered into any
agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of its shares, nor is there an underwriter or
coordinating broker acting in connection with a proposed sale of shares by the
selling stockholder. If we are notified by the selling stockholder that any
material arrangement has been entered into with a broker-dealer for the sale of
shares, if required, we will file a supplement to this prospectus.

        If the selling stockholder uses this prospectus for any sale of the
shares, it will be subject to the prospectus delivery requirements of the
Securities Act. For transactions effected on or through the NYSE, those
requirements may be satisfied by our delivery of copies of this prospectus to
the NYSE in compliance with Securities Act Rule 153. Instead of using this
prospectus for any sale of the shares, the selling stockholder may resell shares
in compliance with the criteria and requirements of Securities Act Rule 144.

        The anti-manipulation rules of Regulation M under the Securities
Exchange Act of 1934 may apply to sales of our common stock and activities of
the selling stockholder.

           this prospectus.

        We have also filed a registration statement on Form S-3 with the SEC
under the Securities Act. This prospectus does not contain all of the
information set forth in the registration statement. You should read the
registration statement for further information about us and our common stock.

        You should rely only on the information contained in this prospectus. We
have authorized no one to provide you with different information. We are not
making an offer of these securities in any state where the offer is not
permitted. You should not assume that the information in this prospectus is
accurate as of any date other than the date on the front of this prospectus.

                           FORWARD-LOOKING STATEMENTS

        We have made forward-looking statements in this prospectus within the
meaning of the federal securities laws. The statements that are not purely
historical should be considered forward-looking statements. Often they can be
identified by the use of forward-looking words, such as "may," "will," "could,"
"project," "believe," "anticipate," "expect," "estimate," "continue,"
"potential," "plan," "forecasts," and the like. Statements concerning current
conditions may also be forward-looking if they imply a continuation of current
conditions. These statements appear in a number of places in this prospectus and
the information incorporated by reference and include statements regarding our
intentions, plans, strategies, beliefs or current expectations with respect to,
among other things:

        -  our financial prospects

        -  our financing plans

        -  litigation and other contingencies potentially affecting our
           financial position or operating results

        -  trends affecting our financial condition or operating results

        -  our strategies for growth, operations, product development and
           commercialization

        -  conditions or trends in or factors affecting the computer, data
           storage, home entertainment or hard drive industry.

        Forward-looking statements involve risks, uncertainties and assumptions.
You should understand that a number of factors could cause our results to differ
materially from those expressed in the forward-looking statements. You are
cautioned not to put undue reliance on any forward-looking statements. Except as
may be required by law, we do not have any intention or obligation to update
forward-looking statements after we distribute this prospectus.

        The information provided in this prospectus or incorporated by
reference, identifies important factors that could cause our results to differ
materially from those expressed in the forward-looking statements. Those factors
include, among others, the highly competitive nature of the hard drive industry,
which is characterized by periods of severe price competition and price erosion,
which can result in shifting market share, and rapid technological changes.

                                  LEGAL MATTERS

        The validity of the shares of common stock covered by this prospectus
was passed upon by Gibson, Dunn & Crutcher LLP, Irvine, California.

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS

        Section 145(a) of the General Corporation Law of the State of Delaware
(the "DGCL") provides that a Delaware corporation may indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative, other than an action by or in the right of the corporation, by
reason of the fact that such person is or was a director, officer, employee or
agent of the corporation or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation or enterprise,
against expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding if he or she acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had no cause to believe his
or her conduct was unlawful.

        Section 145(b) of the DGCL provides that a Delaware corporation may
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses actually
and reasonably incurred by such person in connection with the defense or
settlement of such action or suit if he or she acted under similar standards to
those set forth above, except that no indemnification may be made in respect to
any claim, issue or matter as to which such person shall have been adjudged to
be liable to the corporation unless and only to the extent that the court in
which such action or suit was brought shall determine that despite the
adjudication of liability, but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to be indemnified for such
expenses which the court shall deem proper.

        Section 145 of the DGCL further provides that to the extent a director
or officer of a corporation has been successful in the defense of any action,
suit or proceeding referred to in subsection (a) and (b) of Section 145 or in
the defense of any claim, issue or matter therein, he or she shall be
indemnified against expenses actually and reasonably incurred by him or her in
connection therewith; that indemnification provided for by Section 145 shall not
be deemed exclusive of any other rights to which the indemnified party may be
entitled; and that the corporation may purchase and maintain insurance on behalf
of a director or officer of the corporation against any liability asserted
against such officer or director and incurred by him or her in any such capacity
or arising out of his or her status as such, whether or not the corporation
would have the power to indemnify him or her against such liabilities under
Section 145.

        As permitted by Section 102(b)(7) of the DGCL our certificate of
incorporation provides that a director shall not be liable to us or our
stockholders for monetary damages for breach of fiduciary duty as a director.
However, such provision does not eliminate or limit the liability of a director
for acts or omissions not in good faith or for breaching his or her duty of
loyalty, engaging in intentional misconduct or knowingly violating the law,
paying a dividend or approving a stock repurchase which was illegal, or
obtaining an improper personal benefit. A provision of this type has no effect
on the availability of equitable remedies, such as injunction or rescission, for
breach of fiduciary duty.

        Our bylaws require that directors and officers be indemnified to the
maximum extent permitted by Delaware law. We may, from time to time, enter into
indemnity agreements with each of our directors and officers requiring that we
pay on behalf of each director and officer party thereto any amount that he or
she is or becomes


                                      II-1
<PAGE>   16
legally obligated to pay because of any claim or claims made against him or her
because of any act or omission or neglect or breach of duty including any actual
or alleged error or misstatement or misleading statement, which he or she
commits or suffers while acting in his or her capacity as a director and/or
officer of Western Digital and solely because of his or her being a director
and/or officer. Under the DGCL, absent such an indemnity agreement,
indemnification of a director or officer is discretionary rather than mandatory,
except in the case of a proceeding in which a director or officer is successful
on the merits. Consistent with our bylaw provision on the subject, the indemnity
agreements require us to make prompt payment of defense and investigation costs
and expenses at the request of the director or officer in advance of
indemnification, provided that the recipient undertakes to repay the amounts if
it is ultimately determined that he or she is not entitled to indemnification
for such expense and provided further that such advance shall not be made if it
is determined that the director or officer acted in bad faith or deliberately
breached his or her duty to Western Digital or its stockholders and, as a
result, it is more likely than not that it will ultimately be determined that he
or she is not entitled to indemnification under the terms of the indemnity
agreement. The indemnity agreements make the advance of litigation expenses
mandatory absent a special determination to the contrary. Under the DGCL absent
such an indemnity agreement, such advance would be discretionary. Under the
indemnity agreement, we would not be required to pay or reimburse the director
or officer for his or her expenses in seeking indemnification recovery against
us. By the terms of the indemnity agreement, its benefits are not available if
the director or officer has other indemnification or insurance coverage for the
subject claim or, with respect to the matters giving rise to the claim, the
director or officer:

            (1) received a personal benefit,

            (2) violated Section 16(b) of the Exchange Act or analogous
        provisions of law, or

            (3) committed enumerated acts of dishonesty. Absent the indemnity
        agreement, indemnification that might be made available to directors and
        officers could be changed by amendments to our certificate of
        incorporation or bylaws.

        Our directors' liability insurance policy insures our directors and
officers against the cost of defense, settlement or payment of a judgment under
some circumstances stated in the policy. The selling stockholder has agreed to
indemnify Western Digital and its officers, directors and other controlling
persons against certain liabilities in connection with this registration,
including liabilities under the Securities Act.

ITEM 17. UNDERTAKINGS

        The undersigned registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
        made, a post-effective amendment to this registration statement:

                  (i)    To include any prospectus required by Section 10(a)(3)
                         of the Securities Act;

                  (ii)   To reflect in the prospectus any facts or events
                         arising after the effective date of the registration
                         statement (or the most recent post-effective amendment
                         thereof) which, individually or in the aggregate,
                         represent a fundamental change in the information set
                         forth in the registration statement;

                  (iii)  To include any material information with respect to the
                         plan of distribution not previously disclosed in the
                         registration statement or any material change to such
                         information in the registration statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Securities Exchange Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act that are incorporated by reference
in the registration statement.

               (2) That, for the purpose of determining any liability under the
        Securities Act, each post-effective amendment shall be deemed to be a
        new registration statement relating to the securities offered herein,
        and the offering of such securities at that time shall be deemed to be
        the initial bona fide offering thereof.

               (3) To remove from registration by means of a post-effective
        amendment any of the securities being registered which remain unsold at
        the termination of the offering.

        The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement relating to the
securities offered herein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR
HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT
COVERING SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 UNDER THE
ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE
SECURITIES REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE,
TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.




                           WESTERN DIGITAL CORPORATION
                          COMMON STOCK PURCHASE WARRANT


        THIS CERTIFIES THAT, for value received, Magnetic Media Development,
LLC, a California limited liability company ("Holder") is entitled to purchase
two hundred fifty thousand (250,000) shares of Common Stock ("Warrant Shares")
of Western Digital Corporation, a Delaware corporation (the "Company"), at the
Warrant Price (as defined in subsection 1(j) below) of five dollars ($5.00),
subject to adjustments and all other terms and conditions set forth in this
Warrant.

        1.     Definitions.  As used herein, the following terms, unless the
context otherwise requires, shall have the following meanings:

               (a) "Acquisition" means any sale or other disposition of all or
substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than fifty percent (50%)
of the outstanding voting securities of the surviving entity after the
transaction.

               (b) "Act" shall mean the Securities Act of 1933, as amended, or
any successor federal statute, and the rules and regulations of the Commission
thereunder, all as the same shall be in effect at the time.

               (c) "Commission" shall mean the Securities and Exchange
Commission, or any other federal agency at the time administering the Act.

               (d) "Common Stock" shall mean shares of the Company's presently
or subsequently authorized Common Stock, and any stock into which such Common
Stock may hereafter be exchanged.

               (e) "Company" shall mean Western Digital Corporation, a Delaware
corporation, and any corporation which shall succeed to or assume the
obligations of Western Digital Corporation, under this Warrant.



<PAGE>   2

               (f) "Date of Grant" shall mean January 10, 2000.

               (g) "Exercise Date" shall mean the effective date of the delivery
of the Notice of Exercise pursuant to Sections 4 and 12 below.

               (h) "Holder" shall mean Magnetic Media Development, LLC or any
other person or entity who shall at the time be the registered holder of this
Warrant.

               (i) "Shares" shall mean shares of the Common Stock, as described
in the Company's Certificate of Incorporation.

               (j) "Warrant Price" shall mean $5.00 per share.

        2.     Issuance of Warrant and Consideration Therefor.  This Warrant is
issued in consideration of Holder entering into that certain Final Settlement
Agreement between Holder and the Company dated November 3, 1999.

        3.     Term.  The purchase right represented by this Warrant is
exercisable only during the period commencing upon the date of registration of
the Warrant Shares pursuant to Section 4(d) hereof and ending on the date set
forth in Section 4(d).

        4.     Exercise of Warrant.

               (a) Exercise. This Warrant may be exercised, in whole or in part,
by the Holder hereof by delivery to the Company, at its principal office, the
notice of exercise (the "Notice of Exercise") in the form of Exhibit A attached
hereto, duly executed by the Holder, and in the discretion of Holder, the Holder
may either (1) prior to or concurrent with such delivery place in escrow, with
Salomon Smith Barney or another nationally recognized escrow agent mutually
agreed to by the parties, a payment either in cash or by certified or official
bank check payable to the order of the Company in the amount obtained by
multiplying the number of Warrant Shares for which this Warrant is being
exercised by the Warrant Price then in effect (the "Exercise Price") and this
Warrant, and evidence reasonably satisfactory to the Company of such delivery to
the escrow agent shall be provided with the Notice of Exercise, or (2) accompany
the Notice of Exercise with payment in either cash or by certified or official
bank check payable to the order of the Company in the amount of the Exercise
Price with the surrender of the Warrant to the Company. All costs, fees and
expenses of the escrow agent shall be paid by the Holder.

               (b) Delivery of Certificate. In the event of any exercise of the
purchase right represented by this Warrant, certificates for the Warrant Shares
so purchased shall be delivered to the escrow agent or the Holder, as
applicable, within three (3) days of delivery of the Notice of Exercise and,
unless this Warrant has been fully exercised or has expired, a new warrant
representing the portion of the Warrant Shares with respect to which this
Warrant shall not then have been exercised shall also be issued to the Holder
and concurrently delivered with the certificates within such three (3) day
period. If the Holder has elected to place the Exercise Price and this Warrant
in escrow, the agreement governing the escrow arrangement shall state that


                                       2
<PAGE>   3
upon receipt of the certificates and the replacement warrant, if applicable, the
monies and this Warrant held in escrow shall be immediately released to the
Company.

               (c) No Fractional Shares. No fractional shares shall be issued in
connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment therefor upon the basis of the Fair Market
Value of a share of Common Stock as of the Exercise Date. Fair Market Value of a
share of Common Stock as of a particular date (the "Determination Date") shall
mean the closing price of such Common Stock on the New York Stock Exchange on
such date, as reported in the Wall Street Journal. In the event that such a
closing price is not available for a Determination Date, the Fair Market Value
of a share of Common Stock on such date shall be the closing price of a share of
the Common Stock on the New York Stock Exchange on the last business day prior
to such date or such other amount as may be determined by the Company's board of
directors by any fair and reasonable means.

               (d) Registration or Qualification of Securities. The Company
shall use its best efforts to cause the Shares underlying this Warrant to be
registered under the Act on Form S-3 (the "Registration Event") and listed on
the New York Stock Exchange by May 9, 2000, and in connection therewith shall
prepare and file within 60 days of the date hereof the appropriate form of
registration statement, provided however, that the Holder shall have timely
provided all information and materials for inclusion in the registration
statement relating to the Holder, its predecessors and affiliates or its plan of
distribution for this Warrant or the Warrant Shares and taken all such other
action as may be reasonably required by the Company, in order for the Company to
meet this schedule and to permit the Company to comply with all applicable
requirements of the Act and the Commission. If the Warrant Shares are registered
by May 9, 2000, the term within which this Warrant shall be exercisable shall
terminate at 5:00 P.M. California time on November 3, 2002 (the "Warrant
Expiration Date"). If the Warrant Shares are not registered by May 9, 2000, for
any reason other than the failure of Holder to timely provide the information
and take the actions set forth in this Section 4(d), for each business day that
the Warrant Shares are not registered after May 9, 2000, the Warrant Expiration
Date shall be extended by one business day.

        5.      Adjustment of Warrant Price and Number of Warrant Shares. The
number of securities issuable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the occurrence of
certain events, as follows:

               (a) Adjustment for Dividends in Stock. In case at any time or
from time to time the holders of the Common Stock of the Company (or any shares
of stock or other securities at the time receivable upon the exercise of this
Warrant) shall have received or, on or after the record date fixed for the
determination of eligible stockholders, shall have become entitled to receive,
without payment therefor, other or additional stock of the Company by way of
dividend then, and in each case, the Holder of this Warrant shall, upon the
exercise hereof, be entitled to receive, in addition to the number of Warrant
Shares receivable thereupon, and without payment of any additional consideration
therefor, the amount of such other or additional stock of the Company which such
Holder would hold on the date of such exercise had it been the holder of record
of Warrant Shares on the date hereof and had thereafter, during the period from
the date

                                       3
<PAGE>   4
hereof to and including the date of such exercise, retained such shares
and/or all other additional stock receivable by it as aforesaid during such
period, giving effect to all adjustments called for during such period by
subparagraphs (b) and (c) of this Section 5.

               (b) Adjustment for Reclassification or Reorganization. In case of
any reclassification or change of the outstanding securities of the Company or
of any reorganization of the Company, then and in each such case the Holder of
this Warrant, upon the exercise hereof at any time after the consummation of
such reclassification, change, or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in subparagraphs (a) and
(c); in each such case, the terms of this Section 5 shall be applicable to the
shares of stock or other securities and property receivable upon the exercise of
this Warrant after such consummation.

               (c) Stock Splits and Reverse Stock Splits. If, after the date
hereof, the Company shall subdivide its outstanding shares of Common Stock into
a greater number of shares, the Warrant Price in effect immediately prior to
such subdivision shall thereby be proportionately reduced and the number of
Warrant Shares receivable upon exercise of this Warrant shall thereby be
proportionately increased; and, conversely, if the outstanding number of shares
of Common Stock shall be combined into a smaller number of shares, the Warrant
Price in effect immediately prior to such combination shall thereby be
proportionately increased and the number of Warrant Shares receivable upon
exercise of the Warrant shall be proportionately decreased.

        6.      Termination on Acquisition. This Warrant shall terminate, if not
earlier exercised, in the event of an Acquisition. In the event the Company is
proposed to be acquired, in addition to the notice requirements of Section 7
hereof, the Company shall provide the Holder with all information with respect
to the Acquisition that is otherwise provided to stockholders of the Company at
such time and from time to time during the pendency of the Acquisition,
including (but not limited to) the proposed price to be paid in the proposed
Acquisition. The Holder shall have the right to exercise this Warrant on or
prior to the closing date with respect to the proposed Acquisition; if the
Warrant is not exercised on or prior to such closing date, the Warrant shall
expire upon the occurrence of the closing of the Acquisition.

        7.      Notices of Record Date, Etc. In the event of (a) any taking by
the Company of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend or other distribution (the "Distribution"), (b) any capital
reorganization or reclassification of the stated capital of the Company or any
consolidation or merger of the Company with any other corporation or
corporations (other than a wholly-owned subsidiary), or the sale or distribution
of all or substantially all of the Company's property and assets (the
"Reorganization Event"), or (c) any Registration Event pursuant to Section 4(d)
hereof, the Company will mail or cause to be mailed to the Holder a notice
specifying (i) the date of any such Distribution stating the amount and
character of such Distribution, (ii) the date on


                                       4
<PAGE>   5
which any such Reorganization Event or Registration Event is expected to become
effective, and (iii) the time, if any, that is to be fixed as to when the
holders of record of the Company's securities shall be entitled to exchange
their shares of the Company's securities for securities or other property
deliverable upon such Reorganization Event. Such notice shall be mailed at least
ten (10) days prior to the date therein specified.

        8.     Securities Law Requirements.

               (a) Legality of Issuance. No Shares shall be issued upon the
exercise of this Warrant unless and until the Company has determined that:

                      (1) it and Holder have taken all actions required to
        register the Warrant Shares under the Act;

                      (2) any applicable listing requirements of the New York
        Stock Exchange with respect to the Warrant Shares have been satisfied;
        and

                      (3) any other applicable provisions of state or federal
        law have been satisfied.

               (b) Compliance with Act. The Holder, by acceptance hereof, agrees
and acknowledges (1) that this Warrant is being acquired solely for its own
account and not as a nominee for any other party and not with a view toward the
resale or distribution hereof and that it will not offer, sell or otherwise
dispose of this Warrant except under circumstances which will not result in a
violation of the Act, and (2) that neither the offer nor sale of this Warrant
nor the Shares underlying this Warrant have been registered or qualified under
the Act or any state securities laws on the ground that such offer and sale is
or will be exempt from registration and qualification under Sections 4(2) and 18
of the Act, and that the Warrant and the Shares underlying the Warrant cannot be
offered, sold or transferred except in compliance with the Act.

               (c) Transferability and Negotiability of Warrant. This Warrant
may not be transferred or assigned in whole or in part without the written
consent of the Company and compliance with all applicable federal and state
securities laws by the transferor and the transferee (including the delivery of
investment representation letters and legal opinions reasonably satisfactory to
the Company, if requested by the Company and the transfer is to a person other
than an affiliate of the initial Holder). Subject to the provisions of this
Warrant with respect to compliance with the Act, title to this Warrant may be
transferred by endorsement and delivery in the same manner as a negotiable
instrument transferable by endorsement and delivery. The Company shall act
promptly to record transfers of this Warrant on its books, but the Company may
treat the registered holder of this Warrant as the absolute owner of this
Warrant for all purposes, notwithstanding any notice to the contrary.

        9.      Rights of Stockholders. No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Warrant Shares or any other
securities of the Company which may at any time be issuable on the exercise of
this Warrant for any purpose, nor shall anything contained herein be construed
to confer upon the Holder, as such, any of the rights of a


                                       5
<PAGE>   6
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action (whether upon any recapitalization,
issuance of stock, reclassification of stock, consolidation, merger, transfer of
assets or otherwise) or to receive notice of meetings, or to receive dividends
or subscription rights or otherwise until this Warrant shall have been exercised
and the Warrant Shares issuable upon exercise hereof shall have become
deliverable, as provided herein.

        10.     Replacement of Warrants. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

        11.     Exchange of Warrant. Subject to the other provisions of this
Warrant, on surrender of this Warrant for exchange, properly endorsed and
subject to the provisions of this Warrant with respect to compliance with the
Act, the Company at its expense shall issue to or on the order of the Holder a
new warrant or warrants of like tenor, in the name of the Holder or as the
Holder (on payment by the Holder of any applicable transfer taxes) may direct,
for the number of Shares issuable upon exercise thereof.

        12.     Notices. All notices and other communications from the Company
to the Holder, or vice versa, shall be deemed delivered and effective when given
personally or three days after being mailed by first-class registered or
certified mail, postage prepaid, at such address as may have been furnished to
the Company or the Holder, as the case may be, in writing by the Company or such
Holder from time to time.

        13.    Waiver.  This Warrant and any term hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is
sought.

        14.     Governing Law. This Warrant shall be governed by and construed
in accordance with the laws of the State of California, as such laws are applied
to agreements entered into in California and to be performed solely by
California residents.

        15.     Titles and Subtitles; Forms of Pronouns. The titles of the
Sections and Subsections of this Warrant are for convenience only and are not to
be considered in construing this Warrant. All pronouns used in this Warrant
shall be deemed to include masculine, feminine and neuter forms.

        16.    Expiration.  Subject to the provisions of Section 4 above, the
right to exercise this Warrant shall expire at 5:00 P.M. California time, on
November 3, 2002.

        17.     Form of Warrant. The original text of this Warrant contained
certain omissions and procedural ambiguities, which are corrected by this
version of the Warrant. This version of the Warrant is made effective as of the
Date of Grant, without any additional representations or inducements, solely to
set forth the parties' agreement with respect to the subject matter hereof, and
supersedes all previous versions. Upon receipt of this Warrant by the Holder all
previous versions of the Warrant shall be null and void.

         Re: Registration Statement on Form S-3 of Western Digital Corporation

Ladies and Gentlemen:

         We refer to the registration statement on Form S-3 (the "Registration
Statement") under the Securities Act of 1933, as amended (the "Securities Act")
filed by Western Digital Corporation, a Delaware corporation (the "Corporation")
with the Securities and Exchange Commission (the "Commission") on the date
hereof in connection with the registration under the Securities Act of up to
250,000 shares of the Corporation's common stock, par value $ 0.01 per share
(the "Shares") issued by or to be issued by the Corporation to Magnetic Media
Development, LLC pursuant to that certain Common Stock Purchase Warrant issued
by the Corporation on January 10, 2000 to Magnetic Media Development, LLC (the
"Warrant").

         For purposes of rendering this opinion, we have examined the originals
or certified copies of such corporate records, certificates of officers of the
Corporation and/or public officials and such other documents, including the
Warrant, and have made such other factual and legal investigations, as we have
deemed relevant, necessary or appropriate. In such examination, we have assumed
the genuineness of all signatures, the authenticity of all documents submitted
to us as originals, the conformity to original documents of all documents
submitted to us as conformed or photostatic copies and the authenticity of the
originals of such copies.

         Based on our examination described above, subject to the assumptions
stated above and relying on the statements of fact contained in the documents
that we have examined, we are of the opinion that the Shares have been duly
authorized and when issued, delivered and paid for pursuant to and in accordance
with the terms of the Warrant, will be validly issued, fully paid and
non-assessable.

         This opinion is limited to the General Corporation Law of the State of
Delaware and United States federal law.

         You have informed us that Magnetic Media Development, LLC may sell the
Shares from time to time on a delayed basis. This opinion is limited to the laws
referred to above as in effect on the date hereof and to all facts as they
presently exist.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement, and we further consent to the use of our name under the
caption "Legal Matters" in the Prospectus forming a part of said Registration
Statement. In giving this consent, we do not thereby admit that we are within
the category of persons whose consent is required under Section 7 of the
Securities Act or the Rules and Regulations of the Commission.

                                                Very truly yours,
