Insert recording system for a video signal

摘要

In an insert recording system for a video signal, a tape is recorded with a video signal along tracks formed obliquely with respect to the longitudinal direction of the tape, a part of recorded tracks is erased, and a different or new video signal is recorded onto the erased part. The insert recording system comprises one or a plurality of video heads for recording the different or new video signal onto the erased part of the tape, one or a plurality of flying erase heads mounted on a rotary body provided with the one or a plurality of video heads, at a position leading the video head by an angle theta (in radians) with respect to the rotating direction of the video head, where the flying erase head has a track width wider than the track width of the video head, an erasing current generating circuit for generating an erasing current, a first control circuit for controlling supply of the erasing current to the flying erase head, and a second control circuit for controlling supply of the different or new video signal to video head.
