Abstract
A signal pickup stylus which cooperates with an information storing spiral groove on a video disc record is caused to selectively skip groove convolutions of the disc record to produce special effects including stop, fast-forward and reverse motion of the displayed image. The stylus is coupled to a support arm. Apparatus is provided for establishing relative motion between the stylus and the support arm. This apparatus is made responsive to deviations in the relative position of the stylus and the support arm from a predetermined relationship.
