A device for retrieving selected informational material stored in a groove formed in a rotatable recording element. A stylus, which is disposed above the recording element, is mounted at a fixed, reference position to a transport mechanism which may be moved to position the stylus over that portion of the groove at which the particular information is stored. The device then lowers the stylus into the groove. When in the lowered position, the stylus is permitted limited freedom of movement so that it may track in the groove as the recording element is rotated. After the desired information has been retrieved the stylus is raised to the reference position.
