In an image signal recording system for recording on a recording medium an original image signal corresponding to an original picture which is comprised of a plurality of pixels, the original picture is divided into a plurality of pixel blocks each consisting of a predetermined number of pixels, and image signals each corresponding to the associated pixel block divided are recorded on the recording medium in accordance with a first recording mode and a second recording mode which are mutually different in a recording format. Either of the first and second recording modes is selected on each of the plurality of pixel blocks and a recording mode information signal corresponding to the selected recording mode is generated. There are recorded on the recording medium, the first image information signal or the second image information signal formed and the recording mode information signal generated, on a multiple basis. Thus, it is possible to provide the image signal recording system capable of efficiently recording image signals while suppressing a deterioration of the image quality.
