Abstract:
An actuator latch of a hard disk drive to lock an actuator so that the actuator does not rotate when a magnetic head installed at the actuator driven by a voice coil motor is positioned in a parking region, the actuator latch comprising:a locking protrusion installed at the actuator; a latch member rotatably installed on a predetermined rotation axis, the latch member rotating with the rotation of the actuator when the magnetic head is parked so that a hook intercepts the locking protrusion and prevents the latch member from moving in an opposite direction to the parking direction; and a latch member driving unit including a lever installed at the latch member to join a yoke of the voice coil motor by a magnetic force when intercepting the moving path of the locking protrusion and a coil to form the same polarity as the yoke with current supplied by a power supply installed at the lever, the latch member driving unit rotating the latch member to set free the interception of the movement path of the locking protrusion by the hook.
