ABSTRACT:
A head gimbal assembly (HGA) for a disk drive unit that includes a micro-actuator, a slider and a suspension to load the slider and the micro-actuator. The micro-actuator includes a pair of actuator side arms, a PZT element extending between and connecting the actuator side arms; a rotatable plate positioned between the actuator side arms, wherein the slider is mounted on the rotatable plate; and a pair of connection elements that connect the rotatable plate to the actuator side arms, respectively. The rotatable plate rotates in a first direction when the PZT element contracts and a second direction when the PZT element expands.
