Abstract
An actuator latch apparatus for locking a swing arm of a disk drive is described. The apparatus includes a notch provided at an end portion of the swing arm; a latch lever rotatably installed on the base member and including a hook formed to interfere with the notch when the actuator is locked; a first latch pin applying a torque to the latch lever due to a magnetic force of the magnet in a first direction; a second latch pin extending from the latch lever; an attraction part protruded from an edge of the yoke, the attraction part being magnetized by the magnet and adsorbing the second latch pin when the actuator is locked; and a solenoid coil winding around the attraction part and offsetting a magnetism of the attraction part due to a supply of power when the actuator is unlocked.
