Abstract
A self-winding spring starter for rotating data storage devices. The spring is fixed on one end to a chassis or a cowling. The spring selectively engages the rotating assembly at its other end via a clutch when the rotating assembly is being stopped. The assembly stops, reverses, and fully stops again before being locked into place by a brake. The spring thus winds, unwinds, and re-winds, cocking itself in the appropriate direction for re-start.
