Abstract:
1. 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 read head disposed adjacent a surface of the disk, the read head having a leading end and a trailing end, the disk surface moving from the leading end towards the trailing end during disk drive operation; wherein the tongue includes an actuated portion that is rotated about an axis of rotation by expansion of the first piezoelectric element relative to the second piezoelectric element, and the tongue includes a non-actuated portion that is not rotated by expansion of the first piezoelectric element relative to the second piezoelectric element; wherein the non-actuated portion of the tongue adjoins and forms a bridge between the two outrigger beams, and the bridge 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 at least one head mounting plate that is adhered to the read head closer to the leading end than to the trailing end; and wherein each of the first and second piezoelectric elements has an anchored end that is adhered to the bridge closer to the trailing end than to the leading end of the read head, and each of the first and second piezoelectric elements has an opposing actuated end that is adhered to the actuated portion of the tongue closer to the leading end than to the trailing end of the read head.
