Appeal No. 1998-0204
Application 08/501,542
pending in this application.
The invention relates to a magnetic parking device
for the actuator arm of a disk drive. In particular, looking
at Figure 4, a capture member 100 is provided on the actuator
arm 50 (via arm 55) and a permanent magnetic (located between
pins 76a and 76b) latches capture member 100 (and thus arm 50)
into a parked position. To unlatch arm 50, bucking coil 85 is
energized to produce a neutralizing magnetic field, releasing
capture member 100, and thus actuator arm 50 from its parked
position. Representative independent claim 1 is
reproduced as follows:
1. A magnetic parking device for a disk drive
having a data storage medium mounted on a base, means for
reading information from and writing information to the data
storage medium, and an actuator assembly, including an
actuator body and means for positioning the actuator body,
mounted on said base for selectively positioning the means for
reading information from and writing information to with
respect to the data storage medium, comprising:
a magnetically permeable capture member provided on
the actuator body;
a magnet for providing a first magnetic field
including a first magnetic flux;
a magnetic field containing member defining a path
