Abstract
A radial access mechanism for translating, for example, the optical read/write head of an optical recording/playback apparatus relative to a rotating data storage disk to position such head adjacent a desired data track. Such mechanism basically comprises a stationary guide member defining a segment of a circular path, a roller having a head-supporting access arm rigidly coupled thereto, and means for causing the roller to roll, without slipping, on the inside of the circular path defined by the guide member. By virtue of its design, the mechanism inherently functions to translate the head along a hypotrochoidal trajectory.
