ABSTRACT:
An actuator latching device in a hard disk drive maintains the actuator of the hard disk drive in a parking zone while the actuator is not in operation. The hard disk drive includes: a disk that rotates at a high speed via a spindle motor, an actuator rotatably installed upon a pivot to access the disk, head gimbals having a magnetic head installed at one end of the actuator, a bobbin installed on a bottom portion of the actuator, and a voice coil motor for driving the actuator. The actuator latching device of the hard disk drive includes: a latching member fixedly attached to the bobbin, and a latching unit fixed to a body base. The latching unit includes: a magnet for attaching to the latching member to maintain the actuator in the parking zone, and a solenoid coil for reducing the intensity of and reversing the direction of a magnetic field generated by the magnet.
