Abstract

본 발명의 목적은 VHS 비디오 레코더를 사용하여 고선명 TV 재생을 하기 위하여 주신호뿐만 아니라 보조신호를 기록하는 것이다. 보조신호(Z)는 제1자기층(S1) 아래 놓인 제2자기층(S2)에서 제1자기헤드(K1) 보다 더 큰 캡 길이를 가진 제2자기헤드(K2)에 의하여 기록된다. 본 발명은 고선명 TV 기록설비를 가진 S-VHS 비디오 레코더에서 이용될 것이다.It is an object of the present invention to record not only main signals but also auxiliary signals for high definition TV reproduction using a VHS video recorder. The auxiliary signal Z is recorded by the second magnetic head K2 having a cap length larger than that of the first magnetic head K1 in the second magnetic layer S2 under the first magnetic layer S1. The present invention will be used in S-VHS video recorders with high definition TV recording facilities.
