Abstract: PURPOSE:To easily record and reproduce the signal of relatively high density by substituting a flyback time part for a false signal of which time interval is shorter than the flyback time with the aid of a substitution means and time- extending a video signal with the aid of a time extension means. CONSTITUTION:In the video signal of an NTSC system, a fixed pattern such as a vertical flyback time and a horizontal flyback time having a fixed time interval is substituted for the false V signal and the false H signal of which time interval is shorter than that by a false H insertion circuit 6 and a false V insertion circuit 7 and the flyback time is time-shortened. Then, the time of the video signal is time extended in the same interval. Thus the frequency band of a signal recorded on a magnetic tape 31 can be lowered. Besides, as information quantity is quite the same as before, the signal of high density can be recorded without deteriorating the quality of the video signal.
