ABSTRACT:
Both an audio signal and a video signal are recorded on a video tape (3) by way of a pair of audio heads (Ha1, Ha2) and a pair of video heads (Hv3, Hv4) both mounted on a rotary cylinder (1) of a video tape recorder of helical scan type which can be operated in a standard-time mode and a long-time mode. In the long-time mode, audio tracks (8, 8', 8") are formed successively without having guard bands therebetween, and video tracks (7, 7') are formed upon the audio tracks with guard bands therebetween such that boundaries (L1, L2) between consecutive audio tracks (8, 8', 8") are covered by video track (7, 7'). The audio and video heads are positioned such that the audio heads are advanced by a given angle (T+.theta.) from the video heads in a direction of the rotation of the cylinder, and the distance (X') between the bottom of the audio heads and the bottom of the video heads is determined as a function of a track pitch (P.sub.2), the angular displacement (T+.theta.) between the video and audio heads, and a desired difference (B) between edges of audio and video tracks to be formed in long-time mode. Two other video heads (Hv1, Hv2), which may be used for only the standard-time mode, may also be provided in addition to the above-mentioned video heads.
