A micro-actuator for a head gimbal assembly includes a metal frame including a bottom support integrated with a suspension flexure of the head gimbal assembly, a top support adapted to support a slider of the head gimbal assembly, and a pair of side arms that interconnect the top support and the bottom support. The top support includes a rotatable plate, connection arms that couple the rotatable plate to respective side arms, and an electrical pad support plate that supports bonding pads. A PZT element is mounted to each of the side arms. Each PZT element is excitable to cause selective movement of the side arms.
