Single lever type actuator latch apparatus for disk drive

摘要

An actuator latch apparatus for locking, when an operation of a disk drive is stopped, an actuator including: a swing arm rotatably mounted on a base member; a VCM coil coupled to one end portion of the swing arm; a magnet arranged to face the VCM coil; and a yoke for supporting the magnet. The actuator latch 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.
