Abstract
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.
