Abstract
A head suspension assembly for a disk drive includes a load beam, and first and second piezoelectric elements that are disposed within first and second piezoelectric element receiving windows in a mounting plate, respectively. The load beam includes a plurality of rails that includes first and second outer rails and first and second inner rails, each of the plurality of rails being oriented in the longitudinal direction and being formed or bent out of the load beam plane. The first and second inner rails are disposed between the first and second piezoelectric elements, and the first and second outer rails are disposed not between the first and second piezoelectric elements. The first piezoelectric element is disposed between the first outer rail and the first inner rail, and the second piezoelectric element is disposed between the second inner rail and the second outer rail.
