摘要： 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.

The characteristic is switched by turning on and off the additional capacitor by the switching device. The direct connection of a plurality of equivalent resistors with a plurality of switched capacitors and ordinary capacitors makes up an equalizer. The capacitor making up a switched capacitor is connected with a switching device and an additional capacitor so that the frequency characteristic of the equalizer is switchable by turning on and off the switching device. Each of the capacitors making up the switched capacitors, the capacitors making up the time constant circuits and the additional capacitors has an end thereof grounded.
