Abstract
An image signal recording and reproducing system is arranged to record an image signal on a recording medium and to reproduce a recorded image signal from the recording medium. The system adds a pilot signal having a single frequency to at least one of the horizontal and vertical blanking portions of an image signal, and records the thus-added image signal on the recording medium. Accordingly, it is possible to eliminate time base variations which may occur during recording or reproduction without influencing the image signal.
