Appeal No. 1996-4190
Application 08/311,710
The invention relates to a magnetic disk drive which
records and reproduces data onto/from a magnetic medium by
moving a magnetic head mounted on an actuator arm over the
medium. More particularly, the invention is directed to a
mechanism for fixing the head in place when the disk drive is
not operated. A magnetic body is located on the end of the
actuating arm away from the head. As the arm moves, when
operating, the magnetic body defines a planar locus of points.
A magnet is located on a base and is spaced apart from the
magnetic body in a direction perpendicular to said planar
locus of points. The magnetic body, and hence the arm
carrying the head, is held in a fixed place by the magnetic
field of the magnet, without a physical contact between the
body and the magnet. The invention is further illustrated by
the following claim. Representative claim 8 is reproduced as
follows:
8. A structure for fixing a magnetic head which records
or reproduces data in or out of a medium having a recording
area and a parking area, said structure comprising:
a base on which the medium is mounted;
an arm holding the magnetic head over the medium;
movable means for moving said arm;
