Abstract:
A disc drive having a recording disc rotatable about an axis, a slider supporting a transducing head for transducing data with the disc, and a dual-stage actuation assembly supporting the slider to position the transducing head adjacent a selected radial track of the disc, the dual-stage actuation assembly comprising:a movable actuator arm;a load beam connected to the actuator arm; anda microactuator attached to the load beam, the microactuator comprising:a first bending motor having a first end, a second end, and a longitudinal center between the first and second ends, the first bending motor being responsive to control signals to bend and thereby displace the longitudinal center in a selected direction;a second bending motor having a first end, a second end, and a longitudinal center between the first and second ends, the second bending motor being responsive to control signals to bend complementary to the first bending motor and thereby displace the longitudinal center in the selected direction; anda slider support structure supporting the slider over the disc, the slider support structure being attached to the longitudinal centers of the first and second bending motors.
