<p>A magnetic parking device for locking an actuator in a disk drive (30) over a transducer landing zone (61). A magnetically permeable capture member (100) provided on an actuator arm (50) magnetically interacts with a permanent locking magnet (90) thereby locking a transducer (38) in the landing zone (61). A bucking coil (85) is provided arranged about the permanent locking magnet (90) for passing a current to generate a magnetic field with polarity opposite that provided by the permanent locking magnet (90) to neutralize the magnetic field to release the actuator from the parked state.</p> |
