ABSTRACT:
A system for recording stationary images on a convolution track of a video disk in which a stationary image video signal of at least one frame is optically recorded on the track every revolution of the disk. An audio signal is recorded on portions of the track corresponding to every predetermined number of lines of the video signal. The audio signals are time compressed and are recorded on respective portions of the track corresponding to a predetermined number of lines of the video signal. During the read-out, the audio signals are time expanded. The video signal is reproduced from the video signals recorded in lines immediately preceding the audio signals. In another embodiment the video signal is reproduced with the mean of the video signals immediately preceding and subsequent to lines where the audio signals are recorded.
