PURPOSE:To improve the quality of the picture quality of speed changing reproduction and S/N in the normal reproduction of a VTR by using an A/D converter, a D/A converter, and a memory not only at the time of normal reproducing and speed changing reproducing, but at the time of recording. CONSTITUTION:In the recording mode of the VTR, switches 2a, 2b are connected to R-side, and a video input supplied to an input terminal 1 is converted to a digital signal by the A/D converter 5, and supplied to a Y/C separator circuit 6. The circuit 6 makes use of the memory connected to itself, and effectively separate a luminance signal and a color signal from the inputted video signal. Thus separated luminance signal is returned to an analog signal by the D/A converter 8, and frequency-modulated by an FM modulator 10. Also, the separated color signal is converted to an analog signal by the D/A converter 9, and is made an undercolor signal by a low-frequency converter 11. Then, the frequency-modulated luminance signal and the undercolor signal are synthesized by an adder 12, supplied to a magnetic head 3, and thus recorded on a magnetic tape.
