In an actuator latch used with a hard disk drive to lock an actuator in a non-pivoting position when a magnetic head installed at the actuator is positioned in a parking zone of a hard disk, the actuator latch includes a hooked portion provided at one side of the actuator and having first and second hook steps disposed to face each other, a locking member having a hook portion which is coupled to the hooked portion as the actuator moves to the parking zone, the hook portion coupled to the hooked portion being interfered with the first hook step when the actuator rotate clockwise and with the second hook step when the actuator rotate counterclockwise, and an elastic member elastically supporting the locking member to be capable of rotating and providing a restoring force to the locking member with respect to both clockwise and counterclockwise rotations of the locking member. Thus, when a clockwise or counterclockwise rotational impact is applied to the hard disk drive, the actuator latch restricts rotation of the actuator so that the actuator cannot escape from the parking zone and the hard disk drive can be protected from being damaged.
