Abstract:
A head suspension assembly for a disk drive includes a mounting plate that may include an annular swage boss. A load beam is attached to and extends from the mounting plate in a longitudinal direction. A first piezoelectric element is disposed within a first piezoelectric element receiving window in the mounting plate. The load beam includes a first etched region that is elongated in a transverse direction that is transverse to the longitudinal direction. The first etched region neighbors the first piezoelectric element and is disposed closer to the annular swage boss than is the first piezoelectric element.
