Abstract
A multirecording method in which a multiplex sub-Nyquist-sampling video signal is multirecorded together with a predetermined signal, such as a pilot or audio signal, with no generation of striped-pattern interference in the reproduced picture. In accordance with the invention, the frequency of the predetermined signal is set at m/(2n+1) times as high as the horizontal scanning frequency of the video signal, where n is a natural number of m is a natural number other than an integral multiple of (2n+1).
