Abstract
A method for positioning a composite head comprising a control head and an audio head in a rotary head type magnetic video recording and reproducing apparatus at a precise spacing relative to a mounting position of the rotary head is disclosed. A video signal is recorded intermittently for each group of a predetermined number of video tracks on a reference tape and an audio signal is also recorded intermittently in association with the intermittently recorded video signal. The composite head is adjusted and positioned such that the intermittent relationship existing between a reproduced video signal and a reproduced audio signal is the same as the intermittent relationship existing between the video signal and audio signal during recording.
