Abstract

본 발명은 비데오 카세트 레코더에 관한 것으로서, 서비스 옵션 모드시에 헤드에 의하여 검출되는 엔벨로프의 입구값 및 출구값을 검출한다. 그리고 이 입구값 및 출구값의 비를 OSD로서 표시하여 주므로써 사용자가 헤드의 트래이스 상태를 용이하게 알 수 있게 한다.The present invention relates to a video cassette recorder, which detects an inlet value and an outlet value of an envelope detected by a head in a service option mode. By displaying the ratio of the entrance value and the exit value as the OSD, the user can easily know the state of the head.
