positioning..." is not understood since it is not clear how holding
servo signals for an entire rotation of a disc increases "accuracy in
head positioning."
Further, while Baba does, indeed, provide for a mechanical
shock detector, Baba does not suggest the substitution of stored
tracking signals when shocks are detected. Rather, Baba increases
servo loop gain upon detection of shocks. Therefore, it is not clear
why the skilled artisan would have been led, from the teaching of
Baba, to use a mechanical shock detector in the Ohtake device in such
a manner as to cause the substitution of stored tracking signals for
the real time tracking signals when a shock is detected.
Thus, viewing independent claim 1 as a whole and
considering the teachings of the several references, the examiner has
not, in our view, presented a cogent rationale for combining the
references in a manner so as to result in the claimed subject matter.
Accordingly, no prima facie case of obviousness of the claimed
subject matter has been established and we will not sustain the
rejection of claims 1 through 18 under 35 U.S.C. § 103.
The decision of the examiner is reversed.
