Abstract
본 발명은 테이프의 고속탐색에 관한 것으로, 특히 VCR 또는 DAT에서의 고속 탐색시 테이프의 선속도를 일정하게 유지시키도록 한 테이프 기록/재생장치의 테이프 선속도 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to high speed search of tapes, and more particularly, to a method of controlling tape linear speeds of a tape recording / reproducing apparatus for maintaining a constant linear speed of a tape during a high speed search in a VCR or a DAT.
이러한 본 발명은 주행모드시 테이크업 릴 및 서플라이릴의 반경을 검출하는 릴 반경검출 과정과, 상기 릴 반경검출후 고속탐색지령일 경우 초기 테이프의 선속도를 산출하여 메모리에 저장시키는 초기 선속도 산출 과정과, 상기 저장한 테이프 선속도와 상기 검출한 릴반경을 연산하여 캡스턴 모터의 각속도를 산출하고 그 산출한 각속도로 캡스턴 모터를 제어하여 탐색완료시까지 테이프의 선속도를 일정하게 유지시키도록 하는 테이프 선속도 제어과정을 순차 실행 시킨다.The present invention is a reel radius detection process for detecting the radius of the take-up reel and supply reel in the driving mode, and the initial linear speed calculation to calculate the linear speed of the initial tape to store in the memory in the case of the high speed search command after the reel radius detection And calculating the angular velocity of the capstan motor by calculating the stored tape linear velocity and the detected reel radius, and controlling the capstan motor at the calculated angular velocity to maintain the linear velocity of the tape until the completion of the search. The linear speed control process is executed sequentially.
