is compensated for change in the actual rotation speed, (3).
Examiner points to figure 8.
Turning to Rooke, we find that Rooke teaches in col. 7,
lines 14-21, that figure 8 depicts a disk drive system
allowing a selection of reference signals through a
multiplexor (30). Rooke states that a choice is given between
reference signal 17 originating from the disk pattern and a
reference signal 29 originating from the controller pattern.
We fail to find that Rooke teaches a means responsive to the
monitoring means for controlling the phase locked loop to
adjust the first clock signal to a frequency and phase that is
compensated for changes in the actual rotational speed of the
rotating disk.
We find that Appellant's claim 18 recites "means for
compensating the generated clock signal during the write
operation as a function of the actual rotating speed of the
rotating disk, to produce a corrected clock signal." We note
that Appellant's claim 19 recites "compensating the generated
clock signal during the write operation, as a function of the
actual rotational speed of the rotating disk, to produce a
corrected clock signal." We also note that Appellant's claim
