Abstract: A head gimbal assembly for supporting a disk drive includes a slider, a load beam, a ring gimbal affixed to the load beam, and a flexure. The gimbal includes a curved outer gimbal strut comprising a protrusion located between a first straight section of the curved outer gimbal strut and a second straight section of the curved outer gimbal strut. The flexure includes a first end extending along the load beam through a center region of a longitudinal axis of the head gimbal assembly and second end that includes a plurality of bond pads electrically coupled to the slider.

The gimbal includes a detab, a connector region, a stator region and a central tongue region. The gimbal includes a gimbal tether configured to reduce stress on a first portion of the gimbal by coupling the first portion of the gimbal to a second portion of the gimbal.

Abstract: A microelectromechanical actuator, comprising: a substrate, having a surface; a conductive beam suspended parallel to the substrate, displaceable along an axis normal to the surface of the substrate; a center electrode on the substrate under the beam; a pair of side electrodes on the substrate configured, when charged, to exert an electrostatic force normal to the surface of the substrate on the beam that repulses the beam from the substrate, and exerts a balanced electrostatic force on the beam in a plane of the surface of the substrate, the center conductive electrode being configured to shield the beam from electrostatic forces induced by the side electrodes from beneath the beam, and the center electrode being configured to have a voltage different from a voltage on the beam, to thereby induce an attractive electrostatic force on the beam.
