Abstract
이 발명에 의한 테이프 이송속도가 미지인 경우 테이프 전투영 면적을 이용한 테이프 구동장치의 테이프 잔량 검출방법은 이미 알고잇는 정보를 마이크로 프로세서내의 메모리에 저장하는 단계와, 녹화 스위칭수단으로부터 전달된 속도정보를 입력하여 메모리에 저장하는 단계, 그 저장정보를 이용하여 테이프의 전투영 면적을 산출하여 테이프 잔량을 검출하는 단계로 이루어져서, 테이프 이송속도가 미지일 경우에도 전투영 면적을 이용하여 테이프 잔량을 검출할 수 있으므로 녹화재생중에 필요되는 편집상의 제반문제를 해결하는데 매우 유익한 발명이다.When the tape transfer speed according to the present invention is unknown, the method for detecting the remaining tape amount of the tape drive apparatus using the tape combat area may include storing previously known information in a memory in the microprocessor, and transmitting the speed information transmitted from the recording switching means. Inputting and storing in the memory, and calculating the battle area of the tape by using the stored information to detect the remaining tape, even if the tape transfer speed is unknown to detect the remaining amount of tape using the battle area It is a very advantageous invention to solve all the editing problems required during recording and playback.
