Abstract
A microactuator for a disc drive includes a stator attached to the disc drive support structure, a rotor operatively attached to a slider, the rotor being movable with respect to the stator in a first horizontal plane generally parallel to the surface of the disc, and a vertically arranged magnetic circuit. The magnetic circuit is arranged in a plurality of planes substantially parallel to the first horizontal plane so as to move the microactuator rotor and the slider in the first horizontal plane with a stroke of at least 2 micro-meters in response to a current of no greater than 100 milli-Amps provided to the magnetic circuit.
