Abstract
A disk drive includes a base, an actuator pivotally mounted on the base, a motor and a hub for supporting the disk or disks of the drive. A rotatable member disposed on the base includes a latch that cooperates with a hook on the actuator and a magnet that cooperates with a ferromagnetic segment disposed between the rotatable member and the motor. When the motor does not operate, this rotatable member moves to a predetermined position in which the latch engages a hook portion on the actuator. When the motor does operate, the magnetic field that it generates overcomes the force of the magnet and allows the rotatable member to move out of the locking position.
