摘要：
A disk drive comprises a disk recording medium; an actuator traveling on the surface of the disk recording medium; a lock device vertically movable for locking the actuator when located upward or for releasing the actuator when located downward, composed of an elastic plate spring; a first magnetic-field supply for latching the lock device to the lower position by the action of a first magnetic force; a second magnetic-field supply for latching the lock device to the upper position by the action of a second magnetic force; and a lock device motor to move the lock device to the upper position when a first current supplied or as to move the lock device to the lower position when the second current different from the first current is supplied.
