Appeal No. 97-1647 Page 14
Application No. 08/321,255
We find that Owe, Murata, and Buettner fail to teach or
to have suggested the step of rotating the disc as claimed.
Claim 2 recites in pertinent part “rotating the disc at a ...
rate of rotation which is less than a normal minimum operating
rate ... during the step of heating the spring loaded
flexure.” Comparison of the claim language to Owe, Murata,
and Buettner evidences that the references neither teach nor
would have suggested the claimed chronological relation, viz.,
“during the step of heating the spring loaded flexure.”
As aforementioned, the examiner admits that Owe in view
of Murata does not disclose rotating the disc at a slower
speed to adjust the flexure arm, which would adjust the fly
height. Buettner does not remedy this defect. It discloses
an idle mode in which the rotational velocity of a disk is
reduced to decrease the power consumed by a disk drive. Abs.,
ll. 1-2. Establishment of the mode includes reducing the
rotational velocity of the disk while monitoring the
instantaneous amplitude of a signal indicating clearance
between the surface of the disk and the drive’s head. Col. 5,
