In a system for controlling a tracking position of a rotary head for a VTR which has a rotary head including an audio and video heads, the existence of an audio signal reproduced by the audio head is detected and the tracking control is carried out on the basis of either the level of said audio FM signal when it exists or the level of a video FM signal reproduced by the video head when the audio FM signal does not exist. |
