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.
