Abstract
An actuator latch system of a hard disk drive (HDD) retains a rotatable swing arm of the HDD in place when a magnetic head of the HDD is parked. The actuator latch system includes a portion of the swing arm that defines a notch at an end portion of a swing arm, and a latch lever that has at least one main hook and a rebound hook, and an elastic buffering arm. The latch lever is disposed on the base member adjacent the end portion of the swing arm and is supported so as to be rotatable. The at least one main hook prevents the swing arm from initially rotating in one direction beyond a certain point, and the rebound hook prevents the swing arm from rotating beyond a certain point after the swing arm rebounds upon colliding with the at least one main hook.
