Appeal No. 2001-1211
Application No. 09/070,580
BACKGROUND
Appellants’ invention is directed to a disc drive for disc
storage devices provided with improved seek function by using
adaptive servo gain adjustment. The disc drive includes a head
and a servo circuit which controllably positions the head
adjacent tracks defined on the rotatable disc (specification,
page 3). The servo circuit, as depicted in Fig. 2, includes
demodulator 146 for conditioning the servo information for use by
digital signal processor 148 which, in turn, generates a current
command signal to a coil driver for positioning the head
(specification, page 8).
Independent claim 8 is reproduced as follows:
8. A disc drive, comprising:
a head adjacent a rotatable disc on which a plurality of
tracks are defined; and
position means, operably coupled to the head, for
positioning the head adjacent the tracks of the disc.
The following reference is relied on by the Examiner:
Hashimoto 4,965,501 Oct. 23, 1990
Claim 8 stands rejected under 35 U.S.C. § 102(b) as being
anticipated by Hashimoto.
