Appeal No. 96-3420
Application 08/164,783
The invention relates to controlling the motion of a
servo head from one track position to a second track position
on a disk. The claims all require a procedure or means for
handling the situation where the step of “detecting when the
servo head reaches the second track position” occurs before
the step of “detecting passage of the predetermined access
time.” Appellant argues that the prior art does not disclose
such a procedure or means. Supplemental Reply Brief (Paper
No. 25) at 2. The examiner postulates that such a procedure
would take place in Horie if the head overshot the second
track position and then the seek operation ended after passage
of the predetermined time. Examiner’s Answer (Paper No. 22)
at 5-6.
The examiner’s interpretation of Horie supposes that the
second track position is detected when the head passes over
the second track position en route to an overshoot. The
examiner’s interpretation further supposes a condition in
which such detection could occur before the predetermined time
expires. The examiner’s interpretation even further supposes
Horie has a procedure or means for ending the seek operation
after the time is detected if such a condition were to occur.
