DECISION ON APPEAL
This is a decision on appeal under 35 U.S.C. § 134 from the final rejection of claims 17-19
and 22-25. Claims 1-16 have been cancelled. Claims 20 and 21 have been withdrawn pursuant to
a restriction requirement.
The invention is directed to an apparatus for raising and lowering a floating-type magnetic
head as exemplified by claims 17 and 22 reproduced below.
17. An information processing apparatus comprising:
a rotative driving means for rotating a disc-shaped recording medium;
a floating-type head at least for reproducing information recorded from a recording
medium or for recording information on the recording medium, the floating-type head having
a slider which is floated by an air flow that is directed near the surface of the rotating
disc-shaped recording medium;
a suspension, made of an elastic member, for supporting the floating-type head;
a raising and lowering means for moving the floating-type head away from the
disc-shaped recording medium when the rotation of the disc-shaped recording medium is
stopped and for allowing the floating-type head to approach a floating height above the
disc-shaped recording medium when the disc-shaped recording medium is rotated; and
a control means for controlling the raising and lowering means in such a manner that
the lowering speed at which the floating-type head is brought to the floating height above the
disc-shaped recordin medium is kept slower than a raising speed at which the floating-type
head is moved away from the disc-shaped recording medium.
22. An information processing apparatus comprising:
a rotative driving means for rotating a disc-shaped recording medium;
a floating-type head at least for reproducing information recorded from a recording
medium or for recording information on the recording medium, the floating-type head having
