Abstract

본 발명은 테이프 기록의 최적화 기술에 관한 것으로, 종래의 디에이티에 있어서는 소거하고자 하는 기록 영역이 존재할때 시작 식별신호만 제거함으로서 실제의 기록은 그대로 테이프에 존재하게 되어 서치시 해당영역을 뛰어넘게 하므로 테이프의 이용 효율면에서 상당히 비효율적인 결함이 있었는 바, 본 발명은 이를 해혁하기 위하여 서브 식별신호의 콘트롤 식별신호에서 사용하지 않는 티오씨 아이디와 쇼트닝 아이디를 종료 아이디와 부가 아이디로 대체하고, 마이크로 컴퓨터와 램을 이용하여 불필요한 영역을 소거 및 시프트시키도록한 것이다.The present invention relates to a technique for optimizing tape recording. In the conventional die, only the start identification signal is removed when there is a recording area to be erased, so that the actual recording exists on the tape as it is, so that the tape is skipped over the corresponding area during search. In order to solve this problem, the present invention replaces the TOS ID and the Shortening ID which are not used in the control ID signal of the sub ID signal with the end ID and the additional ID. The RAM is used to erase and shift unnecessary areas.

제3도의 (가)는 본 발명에서 종료식별신호를 도입한 기록 방법에 대한 신호 흐름도이고, (나)는 본 발명에서 종료 식별신호, 부가 식별신호를 이용한 최적화 방법에 대한 신호 흐름도.3A is a signal flowchart of a recording method in which an end identification signal is introduced in the present invention, and (B) is a signal flowchart of an optimization method using an end identification signal and an additional identification signal in the present invention.

Claims

When a program is recorded for the first time, a start identification signal (Start ID) is recorded in a track of a sub code area for a predetermined time, and after the main area, if no signal is detected for a predetermined time, an end identification signal for a predetermined driving time. A recording step of recording (End ID), an entry into an optimization mode for detecting a start identification signal (Start ID) of the recording to be erased, and whether to erase the next recording. The corresponding record that is not confirmed and erased is stored in the RAM, repeated until the end ID signal of the record to be transferred is detected, and then the end of the shifted record is repeated. And an optimization step of recording an additional identification signal (Append ID) in a unit for a predetermined time.
