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.

Claims (2)

재생키이 입력후에 프론트 로더의 안착이 검출되면 서플라이 릴모터를 구동시켜 테이크업 릴펄스의 검출여부와, 테이크업 릴모터를 구동시켜 서플라이 릴펄스의 검출여부를 판별하여, 판별결과 릴펄스가 검출되지 않으면 카세트가 없는 경우로 판단하여 에러를 경보하며, 판별결과 릴펄스가 검출되면 캡스턴을 1배속 재생으로 구동시키면서 패리티 에러의 검출여부를 판별하고, 판별결과 패리티 에러가 검출되지 않으면 노멀 트랙으로 판단하여 1배속 재생을 지속하며 패리티 에러가 검출되면 와이드 트랙으로 판단하여 1.5배속 재생을 수행함을 특징으로 하는 디지탈 오디오 테이프 레코더의 카세트 인식방법.When the front loader is detected after the play key is input, the supply reel motor is driven to detect whether the take-up reel pulse is detected, and the take-up reel motor is driven to determine whether the supply reel pulse is detected. If no cassette is detected, an error is detected and if a repulse is detected, the capstan is driven at 1x speed playback to determine whether or not a parity error is detected. If no parity error is detected, a normal track is determined. A cassette recognition method of a digital audio tape recorder, characterized by continuing playback at 1x speed and reproducing 1.5x playback speed by judging by wide track when a parity error is detected. 제1항에 있어서, 패리티 에러의 검출여부를 판별하기전에 오디오 뮤트를 수행하고, 패리티 에러의 검출여부 판별결과 패리티 에러가 검출되지 않는 경우 및 검출후 1.5배속 재생에 이어서 오디오 뮤트를 해제함을 특징으로 하는 디지탈 오디오 테이프 레코더의 카세트 인식방법.2. The method of claim 1, wherein audio muting is performed before determining whether a parity error is detected, and if the parity error is not detected and the audio mute is released after 1.5x playback after detection. Cassette recognition method of digital audio tape recorder. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
