Abstract: A suspension includes a first actuator arrangement portion and a second actuator arrangement portion. The first actuator arrangement portion includes a load beam frame portion formed of a part of the load beam. Both ends of a first actuator element are supported by the load beam frame portion. The second actuator arrangement portion includes a second load beam frame portion formed of a part of the load beam and a thin plate frame portion formed of a metal base of a flexure. One end of the second actuator element is supported by the second load beam frame portion. The other end of the second actuator element is supported by the thin plate frame portion.

Abstract: A head driving device includes a head supporting portion supporting a head member, a first beam, a second beam, a first piezoelectric unit including a pair of piezoelectric elements, and a second piezoelectric unit including a pair of piezoelectric elements. When voltage is applied to the piezoelectric elements of the first piezoelectric unit, the piezoelectric elements deform, and a distal end of the first beam moves. The piezoelectric elements of the second piezoelectric unit also deform by application of voltage, and moves a distal end of the second beam in a same direction as the distal end of the first beam.

Abstract: A suspension includes a load beam with first and second openings, a flexure including first and second outriggers, and first and second damper members. The first damper member is attached to the load beam and part of the first outrigger that overlaps the first opening of the load beam. The second damper member is attached to the load beam and part of the second outrigger that overlaps the second opening of the load beam. The first opening includes a region which is not covered by the first damper member, and the second opening includes a region which is not covered by the second damper member.
