An actuator locking apparatus for a hard disk drive having a voice coil motor with at least one magnet attached to at least one of an upper yoke and a lower yoke of the voice coil motor to maintain a magnetic head mounted on an actuator of the hard disk drive in a parked state, the apparatus including a coupling protrusion protruding from an end of an arm of the actuator; a contact part protruding from an edge of either the upper yoke or the lower yoke, contacting a surface of the other of the upper yoke or the lower yoke, and having a slot at a height corresponding to a center of the coupling protrusion; a damping member having a coupling hole in which the coupling protrusion is inserted; and a metal piece attached to one side of the damping member and adhering to the contact part due to magnetic force when the magnetic head is parked.
