We reverse.
BACKGROUND
The disclosed invention relates to a superpolishing
process for making a magnetic disk substrate, for use in a
magnetic disk drive, with a surface roughness of less than 4 Å
(Ångstroms).
Claim 13 is reproduced below.2
13. A magnetic disk substrate, said magnetic disk
substrate comprising:
substrate material having a surface roughness of
less than 4A [sic].
The Examiner relies on the following prior art:
Pickering et al. (Pickering) 5,374,412 December 20,
1994
(filed October 13,
1992)
