1. An actuator latch device of a hard disk drive for locking an actuator to prevent movement of the actuator, when a magnetic head installed on the actuator is parked in a parking area of a hard disk, the actuator latch device comprising: a locking protrusion provided on an end portion of the actuator opposite an end on which said magnetic head is installed; a stopping guard having a pair of hooking portions for restricting a pivot range of the actuator by limiting the range of horizontal movement of said locking protrusion; a latch lever pivotally installed on said stopping guard to pivot around an axis; and a latch lever driving means for driving said latch lever, said latch lever being driven by said latch lever driving means to a locking position to prevent the actuator from rotating when said magnetic head is parked in said parking area by moving one end of the latch lever to a position for interfering with the horizontal movement of said locking protrusion.
