ABSTRACT:
In a recording aspect, an image signal is angle-modulated into a first frequency band. A second or third angle-modulated signal is formed by frequency-converting the first angle-modulated signal respectively into a second or a third frequency band on the basis of first or second reference signals generated in the apparatus. The thus formed angle-modulated signal is recorded. In the course of reproduction, the recorded one of the second or third angle-modulated signals is reproduced, frequency-converted on the basis of the first or second reference signals into the first frequency band to provide the first angle-modulated signal, and is then demodulated to restore the image signal.
