Appeal No. 1998-2496
Application No. 08/714,831
15. A magnetic recording disk having an outer surface with a nominal surface
plane for storing magnetically-readable data, said disk comprising:
a layer of glass substrate material having a substantially planar substrate surface;
and
a magnetizable film layer deposited over said glass substrate surface having a
substantially uniform thickness and substantially planar surface which has a disk recording
region and a disk contact start and stop (CSS) region for landing and take-off of a
magnetic head;
said substrate surface having a substrate CSS region below the disk CSS region;
said substrate CSS region having a plurality of regularly-spaced-apart elevations,
each said elevation having a diametral dimension D in the interval from 1 to 100
d
micrometers and rising to a maximum height h < 100 nanometer above said substrate
d
surface; and
each elevation being a smoothly shaped dome and free of surface cracks and
material ejection.
No prior art references of record are relied upon by the examiner in rejecting the
appealed claims.
Claims 15-43 stand rejected under 35 U.S.C. § 112, first paragraph as being
based upon a specification which fails to adequately teach how to make an/or use the
invention, i.e. failing to provide an enabling disclosure. Claims 35-37, 39, 40 and 42 stand
rejected under 35 U.S.C. § 112, first and second paragraphs, as the claimed invention is
not described in such full, clear, concise and exact terms as to enable any person skilled in
the art to make and use the same, and/or for failing to particularly point out and distinctly
claim the subject matter which appellants regards as the invention.
