Abstract
-12- RCA 69,112 TRACK SKIPPER FOR VIDEO DISC PLAYER In a video disc player, a carriage is subject to translatory motion in correlation with radial motion of a playback stylus relative to a disc record disposed on a rotatable turntable. A stylus arm carrying the stylus at one end thereof has the other end secured to the carriage by means of a compliant rubber coupler. A magnetic element is disposed on the stylus arm near its free end. An electromagnet is fixedly mounted in the carriage adjacent to the stylus arm-mounted, magnetic element. The electromagnet is selectively actuated to cause a change in the radial location of the stylus.
