Abstract

An actuator latch apparatus for a disk drive, having a notch positioned at a first end portion of the swing arm, a latch lever rotatably installed in a base member, a first core provided on a second end portion of the swing arm, and a second core provided at a counterbalance of the latch lever. The first and second cores apply a torque to the swing arm and latch lever, respectively, in a first direction by a magnetic force of the magnet. The latch lever has a latch pivot, a latch arm provided at a first side of the latch pivot and having a hook to be caught by the notch when the actuator is locked, and the counterbalance provided on a second side of the latch pivot. The latch arm of the latch lever is elastically deformed when contacted by the swing arm during parking of the head.
