using the control signal 12 and the detection position
signal 11 of each head.
While Kobayashi’s loop gain estimation process identifies a
gain from a control signal for controlling each head to a
detection position signal and stores the identified gain for
correcting the control signal on the basis of the gain at a point
in time when each head is located at each of a plurality of track
positions, the examiner has pointed to nothing in Kobayashi that
discloses or suggests the simultaneous control of each
microactuator “based on the embedded servo information” and
“based on independent movement of another of the plurality of
microactuators.” Kobayashi’s movement does not appear to be
based on the position of other data heads but, rather, on the
stored gain at a particular position on the disk surface.
Since at least this very specific claim limitation has not
been convincingly shown, by the examiner, to be disclosed by
Kobayashi, we will not sustain the rejection of claims 1 and 4
under 35 U.S.C. § 102(b).
With regard to independent claim 5, this claim contains
features similar, although not verbatim, to independent claim 1.
That is, each of the data heads is said to be simultaneously
