Multi-mode magnetic recording system and multi-mode magnetic recording and playback system for VTR

摘要

A multi-mode recording and playback system for VTR records audio signals and video signals and plays them back from audio tracks and video tracks on a magnetic tape by means of a plurality of rotating audio and video heads. A rotating drum around which a magnetic tape is wound carries therewith first to fourth rotary video heads and first and second rotary audio heads in predetermined relations with respect to angle and vertical level. In a desired mode, the audio heads write (read) audio signals in audio tracks, and the video heads write (read) video signals in video tracks, such that the centers of the audio and video tracks substantially coincide with each other.
