본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 회로도,1 is a circuit diagram of the present invention,

제2도는 본 발명 회로도의 각부 파형도.2 is a waveform diagram of each part of the circuit diagram of the present invention.

Claims (1)

자기 테이프의 2개의 트랙에 위치 신호와 주 데이타 신호가 각각 녹음되게 한 후 헤드(H)와 연결된 위치신호 재생회로(I)의 위치 데이타 펄스가 콘트롤신호 발생부(2) 및 펄스 카운터 회로(3)를 통하여 비교회로(5)에 공급되며 선택스위치 (S1-S3)에서 선곡된 상태 신호가 랫치(RT1-RT3)를 통하여 엔코더(4)에서 비교회로(5)에 인가되어 비교된 상태 신호에 따라(A=B) (A〉B) (A〈B) 주행신호 발생부(6)를 제어하여 재생, 되감기, 배속 구동하는 자기 테이프의 자동 선곡 방법.After the position signal and the main data signal are recorded on two tracks of the magnetic tape, the position data pulses of the position signal reproducing circuit I connected to the head H are transferred to the control signal generator 2 and the pulse counter circuit 3. Is supplied to the comparison circuit (5) through the selection switch (S 1 -S 3 ) is applied to the comparison circuit (5) in the encoder (4) through the latch (RT 1 -RT 3 ) and compared (A = B) (A > B) (A < B) A method for automatically selecting a magnetic tape for reproducing, rewinding, and double-speed driving in accordance with the state signal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
