A micro-actuator frame for a head gimbal assembly includes a bottom support adapted to be connected to a suspension of the head gimbal assembly, a top support adapted to support a slider of the head gimbal assembly, a pair of side arms that interconnect the bottom support and the top support, and a micro-actuator mounting structure provided to the bottom support. The micro-actuator mounting structure is constructed and arranged to maintain a substantially constant gap between the top support and the suspension of the head gimbal assembly in use.
