Abstract
PURPOSE:To eliminate the noise the picture at the connecting shooting part or the S/N deterioration, by starting the recording and reproducing in synchronization between the reproduced CTL signal and the recording CTL to be recorded newly along with the phase servo set under the steady mode. CONSTITUTION:Both the output signal of RS-FF27 and the signal extracted out of the picture recording video signal are supplied to RS-FF29, and then the signal featuring the pulse duration according to the phase difference between the reproduced CTL signal recorded on the tape and the recording CTL signal to be recorded newly is delivered. For this signal, the current causing the maximum torque of the reverse turn is flowed to capstan motor 41 for the time equivalent to the pulse duration and via driving circuit 40 of motor 41. Thus the rotational speed is slowed down suddenly to vary the tape running speed and then vary the phase of the reproduced CTL signal. In such way, the phase difference of the both is improved instantaneously, and the phase is matched substantially between the reproduced CTL signal and the recording CTL signal in the case of the timing with which the picture recording is started. As a result, the phase disturbance can be avoided on the channel track.
