Abstract

Given a constant angular velocity, the tangential velocity of a disk past the recording head increases as the distance of the recording head from the center of the disk increases. Therefore, a disk drive requires a means to vary the angular velocity of the disk as the radial position of the recording head changes. The present mechanism provides a constant relative linear velocity between the recording head and the disk, regardless of the radial position of the head.
