Abstract
The invention provides a magneticf actuator lock for the head positioning actuator of a disk drive. The magnetic actuator lock comprises a magnet, and first and second stop means, one of which is attached to the head positioning actuator. The stop means constitute a low reluctance pathway for magnetic flux, thus attracting and 'latching' the two stop means together. This magnetic actuator lock does not require an additional permanent magnet but may use the magnetic force of the permanent magnet in a voice coil motor.
