Ladies and Gentlemen:
We have acted as counsel for Komag, Incorporated (the "Company") which
we understand has filed with the Securities and Exchange Commission a
registration statement on Form S-3 (the "Registration Statement") that relates
to the issuance of certain shares of common stock of the Company (the "Shares")
and other securities of the Company. We further understand that the Shares will
be issued and sold pursuant to resolutions of the Board of Directors of the
Company passed on February 28, 2000 (the "Resolutions").
We have examined such documents, records and matters of law as we have
deemed necessary to the rendering of the following opinion. We have assumed the
genuineness of all signatures, the legal capacity of all individuals and the

Based and relying upon and subject to the foregoing, we are of the
opinion that upon receipt of payment in full therefor in accordance with the
Resolutions, the Shares will be validly issued, fully paid and non-assessable.
