ABSTRACT:
An apparatus for recording a video signal onto tracks of a recording tape includes circuitry for producing a first time-base reference signal which is a color burst signal composed of a first predetermined number of sinewave cycles and a second time-base reference signal which is a burst signal composed of a second predetermined number of sinewave signals. The second predetermined number of cycles is larger than the first predetermined number of cycles. The apparatus further includes superimposing circuitry for superimposing the first time base reference signal on an input video signal at intervals of a horizontal scanning period of the video signal and for superimposing the second time base reference signal on the input video signal at intervals of a predetermined number of horizontal scanning periods of the video signal. The apparatus further includes a modulator for modulating an output signal of the superimposing circuitry to obtain a modulated signal and a recording arrangement for recording the modulated signal onto the tracks of the recording tape.
