ABSTRACT:
When operation mode is switched from recording to pause mode, a magnetic tape on which signals were recorded previously is slightly rewound backward by a predetermined length and is maintained in the pause mode operation state. When the pause condition is released, reproducing operation is performed to detect a phase difference between the reproduced control signal and a control signal of a video signal to be newly recorded. The tape speed is rapidly changed in accordance with the detected phase difference, so that the phase difference between the reproduced control signal and the control signal to be recorded is reduced to zero. Then, when a discontinuous scene recording is performed by switching from pause to recording operation mode, the phase coincidence has been achieved thereby enabling the phase-coincidence recording of video signals. Thus, upon reproducing, a clear picture with no disturbance can be presented even at the interconnection of signals for different scenes.
