发明名称 Video signal reproducing apparatus
摘要 A video signal reproducing apparatus uses a tape on which a video signal has been recorded along tracks disposed obliquely relative to the tape longitudinal direction. The tracks are mutually contiguous, with substantially no space therebetween. The tracks are recorded and formed by a pair of first and second rotating heads having gaps of mutually different azimuth angles. A control signal is also recorded interrelatedly with the start of the formation of each recording track by the first rotating head. A pair of first and second rotating heads have the same mutually different azimuth angles as the first mentioned first and second rotating heads and also have gaps at different height positions in the rotational planes relative to the centers of the track widths. These heads scan the tracks of the tape to reproduce the video signal. A control circuit reproduces the control signal from the tape and carries out a control so that the first rotating head starts scanning from the starting end of the track recorded and formed by the rotating head having the azimuth angle which is the same as the azimuth angle of the first rotating head. The tape transport mechanism is capable of causing the tape to travel at a speed which is different from the speed that is used at the time of recording. At least the second rotating head has a width which is greater than the track width, the width extending from the edge of the track with which scanning is to start to a phase advanced side, with respect to the tape transport direction.
