ることを特徴とするビデオテープレコーダー。[Claims for Utility Model Registration] A tape drive device that runs a tape at a first speed and a second speed that is 1/2 of the first speed; a first video recording and reproducing head whose width is narrower than the track pitch in terms of speed;
a second video recording and reproducing head having a second azimuth angle provided approximately 180 degrees apart from the first video recording and reproducing head; a rotary head device comprising: a video playback head that is arranged with a step difference of 172 of the track pitch from the playback head, is wider than the first video recording and playback head, and has the first azimuth angle; When recording at the first speed, a video signal is supplied to the first and second video recording and reproducing heads to perform full-feed azimuth recording, and when recording at the second speed, the video signal is supplied to the first and second video recording and reproducing heads. Field skip recording is performed by supplying video signals of even or odd fields only to one video recording/playback head, and when playing back a tape recorded at the second speed and a special feature of a tape recorded at the first speed. A video tape recorder characterized in that outputs are derived from the first video recording/playback head and the video playback head during playback.
