ABSTRACT:
A magnetic recording/reproducing apparatus for sequentially recording each of four pilot signals of different frequencies on each video track to be multiplexed with a video signal and reproducing the video signal and the pilot signals at which time the pilot signals are separated from the video signal and used as a tracking signal to control the transport speed of the magnetic tape, wherein upon reproduction the levels of the pilot signals reproduced from the right and left adjacent video tracks are detected and one of the reproduced pilot signals from the right and left adjacent tracks is controlled in its level so that the tape travelling speed is controlled to make the center of the video head scan the same position on the track as upon recording.
