Abstract
A video tape recorder in which video and audio signals of a plurality of channels are simultaneously recorded onto the same tape by using the same tape running mechanism and the signals of a plurality of channels may be simultaneously reproduced from the tape. The video tape recorder of the invention comprises a recording system and a playback system. The recording system includes a recording processing unit for converting the plurality of video signals into recordable signals, respectively; first and second rotary head pairs which are oppositely arranged with respect to a cylinder. Each head has a track width narrower than a recording track pitch and have gap azimuth angles in an opposite relation. Each head records the signals onto the tape and reads out the signals from the tape. The recording system further includes a unit for recording a control signal synchronous with a vertical sync signal included in one video signal onto a control track. The playback system includes a playback processing unit for reconstructing reproduced signals from the rotary head pairs into video signals and a servo unit for reproducing the control signal to control the rotary head pair and the tape run.
