ABSTRACT:
A video signal recording apparatus equipped with circuits to record a time code signal and a control signal relative to a tape position at a speed higher than a normal recording speed, whereby the time required for recording such signals can be widely shortened to reduce the time of the editing operation, hence enhancing the operational efficiency. Furthermore, the frequency of a bias signal is set to be higher than recordable signal frequencies determined in accordance with the normal tape speed, so that undesired generation of noise that may otherwise be derived from such bias signal can be prevented during the reproduction.
