Abstract: RCA 74,358 Apparatus in a video disc player for previewing or scanning information on a record disc. A position sensor detects the position of a playback stylus relative to the carriage assembly for translating the stylus radially across the disc. The position sensor output signals energize a stylus skipper mechanism to translate the stylus a prescribed number of information tracks in accordance with the stylus carriage bias exceeding a threshold value. The carriage is manually moved across the record with the sensor and skipper mechanism cooperating to translate the stylus in consonance with the carriage movement.

Abstract: RCA 74,664 In a video disc system, the picture display is adversely affected by intermodulation distortion occuring in the signals recovered from the disc record. A non-linear circuit, responsive to a bias signal, generates a compensation signal in a diode modulator for cancelling the undesired distortion components of the recovered signal. The resulting distortion after cancellation is measured in a comparator circuit to determine if the distortion has increased or decreased. The comparator circuitry outputs an appropriate signal to bias the non-linear circuit to further reduce the distortion components. A small oscillation is superimposed on this bias signal, which oscillation simplifies the comparator circuitry and forces the circuit to search for an optimum operating point.

Abstract: RCA 74,107 An adaptive video disc record stylus kicker system for inducing limited stylus translation radially across the disc record. Control circuitry responsive to track identification signals recorded on the disc and to player commands evaluates the error between actual kicker induced stylus translations and the programmed kicker induced stylus translations to calibrate the stylus kicker drive signals.
