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 support structure supporting the slider in proximity to a surface of the disc, the support structure being coarsely positionable by a main actuator and including a flex circuit; a microactuator including a stator attached to the support structure and a rotor operatively attached to the slider, the rotor being connected to the stator by at least one flexible beam; a first electrical interconnect between the flex circuit and the stator of the microactuator; a conductive trace on the flexible beam between the stator and the rotor of the microactuator; and a second electrical interconnect between the rotor of the microactuator and at least one bond pad on the slider electrically connected to the transducing head.
