Abstract

본 발명은 녹화에 사용하려는 녹화 대상 테이프의 블랭크 부분을 탐색하여 이미 녹화가 이루어진 부분에 바로 뒤이어 새로운 내용을 녹화하는 방법에 관한 것이다.The present invention relates to a method of searching for a blank portion of a tape to be recorded for use in recording and recording new contents immediately after the recording portion.

현재 데크(18)에 장착된 테이프로부터 녹화된 부분의 끝 위치를 찾기 위하여 데크(18)를 콘트롤 신호가 검출되지 않는 위치까지 고속 전진(FF)시키는 한편, 그 테이프로부터 현재 콘트롤 신호가 검출되어 있지 않으면, 블랭크 부분의 시작 위치를 찾기 위하여, 데크(18)를 콘트롤 신호가 검출되는 위치까지 고속 후진(REW)시킴으로써, 공백 부분부터 새로운 내용을 녹화시킬 수 있다.In order to find the end position of the recorded portion from the tape currently mounted on the deck 18, the deck 18 is fast forwarded (FF) to a position where the control signal is not detected, while the current control signal is not detected from the tape. Otherwise, in order to find the start position of the blank portion, by reversing the deck 18 to the position where the control signal is detected, new contents can be recorded from the blank portion.
