ABSTRACT:
A micro-actuator for a head gimbal assembly includes a support structure and a PZT element. The support structure includes 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 leading beam that couples the bottom support and the top support. The leading beam includes a weak point that allows the top support to rotate about a rotational axis in use. The PZT element is mounted between the top and bottom supports. The PZT element is excitable to cause selective rotational movement of the top support about the rotational axis in use.
