ABSTRACT:
A video signal recording apparatus has a motor for rotating a magnetic disc at low or high speed, a recording/playback head for recording audio signals on a single first track while the magnetic disc is rotated at the low speed, and a recording head for recording audio signals reproduced from the first track and video signals of one frame. The audio signals are time-base compressed and are reproduced while the magnetic disc is rotated at the high speed. The audio signals are superposed on the video signals to produce a composite signal, thereby recording the composite signal on a single second track.
