Abstract
Apparatus for fixturing an optical recording disc in a DRAW recording machine comprising a hub having a conical shoulder for receiving and locating the disc center opening, and an axially facing shoulder for nesting support of the recording disc. A retaining ring encircles the disc periphery and has an inwardly oriented lip for capturing the disc periphery. A resilient snubber of elastomeric construction extends from the hub to the ring and has a roughened axially facing surface spaced from the opposing surface of the disc. A knob, including a torque-isolating thrust bearing, clamps the hub to the drive spindle of a recording apparatus. In operation, the snubber and air space between the snubber and disc cooperate to dampen vibration of the recording disc for enhanced accuracy and reliability of the recording process.
