ABSTRACT:
The specification describes an audio-visual reproduction device for transmitted light recordings of picture, audio and control signals, in a spiral on a disc-shaped information vehicle. Adjacent to the information vehicle there is an arrangement, including on one side an illuminating device and on the other side an optical sensing device for the signals. Furthermore means are provided by which the signals from the information vehicle are converted into pulses processed by a TV receiver. Displacements of the vehicle in the direction perpendicular to its plane are compensated for on the basis of optical signals. Picture, audio and control signals of the information track are continuously projected on to a single line photodiode array by an objective, which is caused automatically to follow the vertical displacements of the information vehicle, that is to say such displacements as occur perpendicularly to its plane. The information track has a strip-like control track for compensating for vertical displacements. Means are provided for resetting the lateral drift of the light cone which is incident on the photodiode array from the objective, in accordance with the illumination of diodes intended for the compensation of the horizontal displacements of the information vehicle by virtue of the signal track associated with these diodes. Means are provided for follow-up of the objective in accordance with the illumination of the diodes intended for the compensation of the vertical displacements of the information vehicle by means of the control track associated with these diodes.
