position error signal, the position error signal having been
obtained from the servo area.
The examiner never explains just what portions of Brown
are being relied on for the teaching of adding a first offset
amount during a write operation and adding a second offset
amount during a read operation wherein the two offsets are non-
zero in magnitude and of opposite directions. The mere
reference, at page 5 of the answer, to Figure 7 of Brown is
insufficient to establish obviousness of the instant claimed
subject matter. Later, at page 8 of the answer, in response to
appellants’ arguments, the examiner points to column 3, lines
45-50 of Brown. While this section of Brown mentions the
calculation of distance and the summing of this distance with a
read/write centerline offset so that an actual repositioning
distance can be determined, we are at a loss as to how this
disclosure relates to the language of instant claim 1 and the
examiner has not applied this disclosure to the specific claim
language. Accordingly, we find that the examiner has not
established a prima facie of obviousness with regard to the
subject matter of claim 1.
