Abstract
A disc drive has a recording disc rotatable around 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 includes a movable actuator arm, a suspension assembly supported by the actuator arm and including a flexure, a tongue supporting the slider, and a microactuator. The microactuator includes a rotor attached to the tongue and a stator attached to the flexure and operatively connected to the rotor to radially move the rotor with respect to the stator. At least one beam is attached between the slider bond pad and the stator.
