Appeal No. 1998-0204
Application 08/501,542
Sampietro, et al. fails to provide a
disclosure of any apparatus that has a structure or
operation that is the same or equivalent to the
aforementioned embodiment of Applicants’ control
means. (Brief-page 17.)
We have reviewed Appellants’ specification and
drawings to determine the exact control structure disclosed,
and what would constitute reasonable equivalents thereof. At
page 22, lines 16-22, Appellants’ specification states:
Control electronics suitable for use in
accordance with the disk drive described herein are
described in U.S. Patent No. 4,979,056. To control
bucking coil 85, circuitry for controlling the
bucking coil to release the actuator coil may be
included in the control electronics. A block
representation of such circuitry is shown in Figure
9.
As described in Appellants’ specification and Figure
9, a microprocessor, depicted by a block in Figure 9, controls
the timing of when (i.e., simultaneously) the two currents
begin. Turning to Sampietro, we note “...for later connection
to the control logic (not shown) needed to activate the
[bucking] coil 60.” (emphasis added) (column 6, lines 4-5).
Thus, Sampietro discloses control logic to activate the
bucking coil. There can be little dispute, or at least it
would have been very obvious, that known disk drives such as
