ABSTRACT:
A video disc player having an adaptive bumper apparatus which tracks the signal pickup stylus to maintain a fixed spatial relation therebetween. The bumper is fixed to an electromechanical transducer secured to the stylus arm support carriage. Signals correlated to the relative disc-stylus velocity having frequency components of the once around rate of the disc are adapted to energize the transducer to cause the bumper to follow the motion of the stylus in the radial dimension. Disturbing visual effects resulting from disc defects, etc. which tend to kick the signal pickup stylus fore or aft of the current track position are significantly reduced.
