Abstract
A dual-stage actuation assembly for a disc drive includes a movable actuator arm and a load beam connected to the actuator arm. A microactuator is attached to the load beam, and includes a first bending motor, a second bending motor and a slider support structure supporting a slider over the disc. The slider support structure is attached between the first and second bending motors. The first and second bending motors are responsive to control signals to translationally move the slider support structure with respect to the load beam, to finely position a transducing head carried by the slider over a selected track of the disc.
