In the system, a series of signal portions each representing at least one field of the video signal and spaced from each other by a time which is p times (p is an integer) the length of one field are successively concentrically recorded on the disc or cylinder, and the concentrically recorded tracks are successively reproduced while repeating the reproduction on each track a plurality of times.
