Abstract

PURPOSE: To enable to perform signal processing with one set of VTR, by providing the simultaneous recording and reproducing function through the provision of magnetic heads of reproduction, recording and erasion while holding a given angular interval.
CONSTITUTION: In the rotating magnetic head, the recording magnetic heads RA, RB are fitted while holding almost 180° of angular interval, the reproduction magnetic heads PA, PB are fitted with the same angle as the recording magnetic heads RA, RB, and they are fitted apart from the magnetic heads RA, RB by the interval corresponding to 4n-lines of tracks toward rotating shaft. The erasion magnetic heads EA, EB are ahead the recording heads RA, RB by 1/4 rotation, and the video signal SA relating to the track T5 reproduced at the reproduction magnetic head PA is synthesized with the external video signal SB, and the synthesized video signal S0 is recorded on the track T1 with the recording magnetic head RA.
