Abstract
A head suspension mechanism having a load beam and a layer of piezoelectric material on at least one surface of a resilient portion of the load beam adjacent an arm of an actuator in a hard disk drive. A controller apparatus provides a control signal to the piezoelectric material to induce a piezoelectric effect of the piezoelectric material which causes the load beam to raise the head slider from the surface of a disk in a start mode before the disk begins to rotate, and also causes the load beam to keep the head slider from contacting the surface of a disk until the disk comes to a complete stop in a stop mode.
