摘要： A micro-actuator for a head gimbal assembly includes a support frame including 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, and a leading beam that couples the bottom support and the top support. The leading beam includes weak points or notches that allow the top support to rotate about a rotational axis in use. A first PZT element is mounted between first sides of the top and bottom supports, and a second PZT element is mounted between second sides of the top and bottom supports. The first and second PZT elements are excitable to cause selective rotational movement of the top support about the rotational axis in use.

摘要： A micro-actuator for use with an HGA and/or disk drive device (e.g., a small platform disk drive device) with the micro-actuator having a reduced mass suitable for improving shock performance, and/or methods of making the same are provided. In certain example embodiments, the micro-actuator may comprise a substantially U-shaped frame including a cavity capable of receiving a slider, with the frame including two side arms and a bottom support arm at least partially defining the cavity. The bottom support arm may have a reduced mass capable of providing improved shock performance and capable of conveying a high resonance frequency response at a low gain. The bottom support arm may be, for example, substantially rectangle shaped, substantially I-shaped, toothed, etc. Also, the bottom support arm may be less thick than the side arms.
