Appeal No. 1999-0043
Application 08/599,875
We do not see how Daniels and Gilovich are proposed to be
combined to produce the claimed invention. Daniels shows
multiple heads 18, 18', 18", etc. spaced equally around a
single data track. Daniels indicates that each head may be
more than one head, depending on the number of tracks
involved; thus, at each angular head location, there would be
a number of heads located along the radius, one for each
track. It is logical that the fixed heads lying along a
radius, one per track, could be replaced by a single head
affixed to an actuator that would read all tracks or an
actuator with two heads each reading half the tracks, as
taught by Gilovich (although this does not seem to be the
Examiner's rationale). This would still require 10 actuators,
one for each angular location. Daniels teaches the general
concept of switching to a head which is closer to the target
position along a circumferential direction. If the fixed
heads in Daniels were replaced with the movable heads of
Gilovich, this would still result in selecting one of 10
movable heads circumferentially spaced around the disk as the
closest head. Daniels does not teach or suggest modifying the
read/write control of Gilovich so as to switch the data
