Abstract
A magnetless rotary actuator for carrying one or more read/write heads across a data bearing medium, the rotary actuator comprising: a stator including a plurality of independently controllable flux generating means for directing flux between the stator and a rotor; the rotor including means for presenting discrete regions of low magnetic reluctance to the controllable flux generating means; torque coupling means for transmitting operative torque from the rotor to the read/write head; and pivot means for supporting the torque coupling means.
