Patent ID: 8797691

Claim:
A disk drive comprising: a disk drive base; a spindle attached to the disk drive base; a disk mounted on the spindle; a first actuator pivotally attached to the disk drive base, the first actuator including a conductive coil and an actuator arm; a head suspension assembly comprising a load beam having a proximal region that is attached to the actuator arm and a distal region that includes a dimple; a laminated flexure comprising a dielectric layer between a structural layer and a conductive layer, the conductive layer being patterned to include a plurality of conductive traces, the structural layer including a tongue disposed between two outrigger beams; and a single piezoelectric element adhered to the tongue, there being no other piezoelectric element adhered to the tongue; and a read head adhered to the tongue and disposed adjacent a surface of the disk; wherein the tongue includes an actuated portion that is rotated about an axis of rotation by expansion of the piezoelectric element, and the tongue includes a non-actuated portion that is not rotated by expansion of the piezoelectric element; wherein the non-actuated portion of the tongue adjoins the two outrigger beams, and the non-actuated portion includes a dimple contact location that is in contact with the dimple of the load beam, the axis of rotation passing through the dimple contact location; wherein the actuated portion of the tongue includes first and second head mounting plates that are each adhered to the read head, each of the first and second head mounting plates being connected to the non-actuated portion of the tongue by an elongated compliant member that is oriented radially with respect to the dimple contact location; and wherein the piezoelectric element has an anchored end that is adhered to the non-actuated portion of the tongue, and has an opposing actuated end that is adhered to the actuated portion of the tongue.
