Abstract
본 발명은 디지탈 오디오 테이프(DAT)레코더의 카세트 인식을 통한 카세트 테이프 유무판단 및 캡스턴 모터의 배속제어에 관한 것으로 종래에는 인식스위치(2,3)의 기계적 온/오프 작동에만 의존하므로 인식스위치 불량에 따라 인식에러가 발생되기 쉽고 이로 인하여 기기제어에 오류가 발생되는 문제점을 해결하기 위한 것이다.The present invention relates to the determination of the presence or absence of a cassette tape through the cassette recognition of a digital audio tape (DAT) recorder and the speed control of the capstan motor. Therefore, it is easy to recognize an error and thereby solves a problem that an error occurs in device control.
본 발명은 DAT카세트 인식스위치로부터 카세트 정보를 해독하지 않고 릴펄스를 검색하여 카세트 유무를 판단하고, 테이프 주행속도를 기준으로 한 패리티 에어신호를 검색하여 트랙피치를 판단하므로서 카세트 정보를 정확히 검색하고 기기제어에 신뢰성을 확보할 수 있도록 한 것으로 DAT레코더에 적용한다.The present invention accurately retrieves cassette information by searching for reel pulses without deciphering cassette information from the DAT cassette recognition switch, and determining the presence or absence of a cassette, and searching the parity air signal based on the tape traveling speed to determine the track pitch. It is applied to DAT recorder to ensure reliability in control.
