Abstract
A head gimbal assembly (HGA) for a disk drive includes a mounting plate configured to be attachable to an actuator arm, a load beam extending from the mounting plate, a laminated flexure, first and second piezoelectric elements, and a read head. The laminated flexure includes a fixed portion that is attached to the load beam, and a head mounting tongue that is connected to the fixed portion by first and second compliant members. The read head is bonded to the head mounting tongue. The laminated flexure also includes first and second piezoelectric element receiving windows, each adjacent a respective one of the first and second compliant members. The first and second piezoelectric elements are each disposed within a respective one of the first and second piezoelectric element receiving windows.
