1. A structure for supporting a slider from a suspension arm, the structure comprising:

  • a microactuator for finely positioning the slider above a surface of a storage medium; and

    a microactuator suspension attachable to the suspension arm, the microactuator suspension comprising;

    a slider attachment pad;

    a first resilient support extending from the slider attachment pad, wherein the first resilient support is flexible and resilient in an x-direction, is comparatively rigid in a z-direction, and damps vibration of the microactuator suspension to provide the microactuator with sufficient stroke to compensate for vibration of the suspension at frequencies up to about 21,000 hertz; and

    a suspension arm attachment pad extending from the first resilient support.
