| Zusammenfassung: | A gimballed air puck is used in a video disc mastering system for controlling the depth to which an electromechanical stylus cuts into a metal substrate surface. Air is directed through the air puck toward the substrate surface to maintain the cutting stylus at a given cutting depth. The air puck is gimballed or swivelled to permit the cutting stylus to follow the undulating surface of the substrate during the mastering operation. |
