ABSTRACT:
In an actuator latch device of a hard disk drive for locking an actuator to hold a magnetic head parked in a parking area, the actuator latch device includes a locking protrusion provided on an end portion of the actuator, a stopping guard having left and right side hooking portions for restricting a pivot range of the locking protrusion, a latch lever rotatably installed on the stopping guard for locking the actuator which rotates in one direction to have the magnetic head positioned in the parking area, and for preventing the actuator from moving back in the opposite direction, by moving one end of the latch lever to a position for interfering with the locking protrusion when the the head is parked, and a latch lever driving means for driving the latch lever between a locking position and an unlocking position. Thus, since locking and unlocking is performed by selectively restricting movement of the locking protrusion provided on the actuator, a locking state can be firmly maintained and unlocking is performed smoothly without any impact.
