ABSTRACT:
A disk drive suspension for mounting to the end of an actuator arm includes a load beam having a mounting region, a rigid region, and a spring region between the mounting region and the rigid region. The load beam also has a stationary section including first and second outer stationary portions with an open region formed therebetween, a moving section including an inner moving portion located in the open region between the first and second outer stationary portions, and a gap separating the stationary section and the moving section. The gap has first and second gap portions separating the inner moving portion from the first and second outer stationary portions, respectively. The suspension further includes a flexure for receiving and supporting a read/write head, first and second resilient members extending from the first and second outer stationary portions, respectively, across the gap to couple the stationary section to the moving section, and a third resilient member spaced laterally inward from the first and second resilient members and longitudinally located between the first and second resilient members and the proximal end of the load beam. The suspension also includes a piezoelectric microactuator having a first piezoelectric element extending across the first gap portion and coupling the first outer stationary portion to the inner moving portion, and a second piezoelectric element extending across the second gap portion and coupling the second outer stationary portion to the inner moving portion.
