ABSTRACT:
A stylus assembly for use with a high density information record such as a grooved video disc. The stylus arm includes a first transducer for detecting lateral forces applied by the record groove to the pickup stylus, and a second transducer responsive to signal generated by the first transducer to translocate the stylus and thereby reduce said forces. The adaptive elimination of lateral forces to the stylus reduces stylus and disc wear and reduces the probability of record imperfections causing the stylus to radially skip over grooves.
