Abstract
Compact, high-speed, low-mass, rotary actuator structure (and a related method) for manipulating the position of a read/write transducer in a disk-drive system. The actuator includes a motor with a winding distributed in such a fashion that circumscribes, or alternatively semi-circumbounds, the rotary axis of the actuator, thus to assist in providing appropriate mass balance. Electrical connections to this winding, and to other components carried for motion by the actuator structure, extend in a low-torque fashion on and substantially coincidentally along the rotary axis of the actuator.
