Abstract

본 발명은 자기 녹재기의 캡스턴 모터를 구동시키기 위한 스텝/슬로우 펄스의 기동시기 처리방법에 관한 것인 바, 그 특징은 테스트 모드인가를 판별하여 테이프의 유무를 확인하는 제1단계와, 상기 제1단계에서 테스트모드이고 테이프가 안착되어 있으면 슬로우 이동을 실시하면서 엔벨로프 중심치와 그 오토트래킹을 위한 엔벌로프 근사치를 설정하여 엔벌로프를 읽어들이는 제2단계와; 상기 제2단계에서 읽어들인 엔벌로프를 체크하면서 근사치를 중심치로부터 가감하여 헤드가 제일 정확하게 궤적을 추적하는 엔벌로프 근사치를 자동 트래킹에 의해 찾아내는 제3단계와, 상기 제3단계에서 찾아낸 엔벌로프 근사치를 메모리에 저장하여 스텝/슬로우 이동을 위한 기동시기(제1시간)로 설정하는 제4단계로 이루어짐에 있다.The present invention relates to a method for processing a start time of a step / slow pulse for driving a capstan motor of a magnetic ruster, characterized by a first step of determining whether a tape is present by determining whether it is in a test mode, and A second step of reading the envelope by setting an envelope center value and an envelope approximation value for auto tracking while performing a slow movement when the tape is seated in the first step; A third step in which the envelope approximation value, which checks the envelope read in the second step, is added or subtracted from the center value to find the envelope approximation value by which the head tracks the trajectory most accurately by automatic tracking; and the envelope approximation found in the third step. Is stored in the memory and is set as a start time (first time) for step / slow movement.
