Abstract
A slider assembly is operable to selectively alter a position of a transducing head with respect to a track of a rotatable disc having a plurality of concentric tracks. The slider assembly includes a slider wafer arranged to be supported by a disc drive support structure. A stator is bonded to the slider wafer, with the stator including at least one electrode. A rotor is bonded to the stator, with the rotor having a frame portion bonded to the stator and a head-carrying portion attached to the frame portion by a flexible beam structure. The head-carrying portion of the rotor carries the transducing head, supports at least one rotor electrode adjacent to the at least one stator electrode, and is movable with respect to the frame portion of the rotor in response to a voltage difference between the at least one rotor electrode and the at least one stator electrode.
