Abstract
An image signal recording apparatus for recording, on a recording medium, image signals corresponding to an image in which one picture is composed of a plurality of horizontal scanning lines is arranged to store the image signals for one picture, to simultaneously output N kinds (N: an integer at least 2) of image signals corresponding to N number of horizontal scanning lines adjacently located on the picture, and to simultaneously record, in different areas on the recording medium, the N kinds of image signals. This arrangement enables the apparatus to record an image signal of a high picture quality on the recording medium with a high degree of density.
