Appeal No. 1995-3903 Page 9
Application No. 08/062,737
We find that invention of independent claims 37 and 43
does not define over Moon. The claims specify in pertinent
part scheduling “the initiation of each of said plurality of
processes so as to maintain said initiation of each of said
processes in a constant spatial relationship to said predict
present sector period thereby minimizing the effect of
variations in the rotational speed of said rotating media and
synchronizing the initiation of said processes to said sector
mark for the present sector.” Giving the claims their
broadest reasonable interpretation, they recite scheduling
tasks to maintain their initiation in a constant spatial
relationship to a sector period.
Moon discloses a disk file subsystem 10 for storing and
retrieving data. Col. 7, ll. 15-17. A DC spindle motor 16
rotates disks 22 at an angular velocity. Id. at 60-65. Head
transducers 24 write and read data stored on each of the
disks. Col. 8, ll. 2-4. Each surface of the disks comprises
concentric data tracks 50. Each data track is divided into
thirty two equal sectors 52. Col. 9, ll. 14-15, 22-23. Each
sector includes a qualification area 250 followed by a user
data region 54. Id. at ll. 24-27, col. 13, ll. 25-27. The
