ABSTRACT:
A ferromagnetic body is attached or embodied within the actuator arm in a disk drive. The ferromagnetic body is positioned so that the magnets of the voice coil motor attract the ferromagnetic body and produce a force to move the actuator arm so the read/write head attached thereto lands in the landing region of the disk in the event of a power interruption.
