    Abstract: A disc drive data storage system is disclosed that includes a disc storage medium having a disc surface. The system also includes an armature and a slider coupled to the armature. The slider supports a transducer head that communicates with the disc storage medium. The slider flies above the disc surface and positions the transducer head proximate the disc surface. Data representing a topography map of the disc surface is stored in a memory. A controller controls the fly height of the slider above the disc surface as a function of the topography map of the disc surface.

    Abstract: A slider for carrying and finely adjusting both a radial position and a flying height of a transducing head with respect to a track of a rotatable disc includes a stator portion carried by a support structure such as a flexure of a disc drive system. A plurality of springs extend from the stator portion and are flexible in a lateral direction (for radial positioning) and in a vertical direction (for flying height control). A rotor portion is connected to the stator portion by the plurality of springs. The rotor portion carries the transducing head. The stator portion includes a plurality of stator electrodes, and the rotor portion includes a plurality of rotor electrodes suspended between the stator electrodes. Selected voltages are applied to the stator electrodes and the rotor electrodes to create a selected force in the lateral and vertical directions for moving the rotor portion with respect to the stator portion to finely adjust the radial position and flying height of the transducing head.

    Abstract: A method is used for moving a transducing head between tracks of a disc in a dual-stage actuation assembly. The dual-stage actuation assembly has a main actuator for coarse positioning of the transducing head and a microactuator for fine positioning of the transducing head. The method comprises accelerating the main actuator during coarse positioning of the transducing head and applying control pulses to the microactuator during coarse positioning by the main actuator to eliminate oscillation of the microactuator during and after coarse positioning.

    Abstract: A microactuator is built at the slider level to achieve high resolution positioning of a transducing head with respect to a track of a rotatable disc having a plurality of concentric tracks in a disc drive system. The slider includes a main body carried by a flexure. A stator portion extends from the main body, and a plurality of beams extend from the stator portion, the beams being flexible in a lateral direction. A rotor portion is connected to the stator portion by the plurality of beams, forming a gap between the stator portion and the rotor portion. The rotor portion carries the transducing head. A plurality of stator electrodes are formed on the stator portion, and a plurality of rotor electrodes are formed on the rotor portion to confront the stator electrodes across the gap. Control circuitry applies selected voltages to the stator electrodes and the rotor electrodes to create a force in the lateral direction for moving the rotor portion with respect to the stator portion of the slider, thereby finely positioning the transducing head.

    Abstract: The present invention relates to a microactuator having a cavity into which a slider is inserted. Overhanging the cavity are flexible tabs, which are deformed once the slider is inserted. The tabs allow the slider to be aligned in the slider cavity. The tabs also create a mechanical and electrical connection between the slider and the microactuator.
