Abstract
PURPOSE: To enable the recording of high density and long time and high speed reproduction and to obtain the demodulated video signal of good quality, by locking the frequency and phase of carrier of modulated video signal to the horizontal synchronizing signal of the input video signal.
CONSTITUTION: The input video signal from the terminal 21 is in amplitude modulation 23, and the residual side band SD suppressing lower carrier as the modulated video signal is picked up 26, and this is recorded on the magnetic recording media with the rotary heads 4 and 5. In this case, the frequency and phase of the carrier forming modulated video signal are locked 42 to the horizontal synchronizing signal PH of the input video signal. Thus, excellent demodulated video signal can be obtained and the recording of high density and long time and also high speed reproduction can be made.
