Claim:
A hard disk drive comprising: a base; a pivot fixed to the base and having a central axis; an actuator arm, and a read/write head supported by the actuator arm at one end of the actuator arm; a pivot holder mounted to the pivot so as to be rotatable about the axis of the pivot, the actuator arm extending from one side of the pivot holder so as to rotate with the pivot holder; a bobbin extending from a side of the pivot holder opposite the side from which the actuator arm extends; a voice coil motor including a voice coil extending along the bobbin, and a magnet fixed to the base and juxtaposed with the voice coil, wherein the voice coil motor generates an electromagnetic force to rotate the actuator arm about the axis of the pivot when current flows in the voice coil; and a magnetic retractor situated at and integrated with the pivot holder, wherein a magnetic force is generated between the retractor and the magnet of the voice coil motor.
