VCR의 자동 트래킹 장치VCR Auto Tracking Device

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

제 3 도는 본 발명에 따른 회로도, 제 4 도는 본 발명의 영상 헤드 배치도, 제 5 도는 본 발명의 영상 헤드 배치도.3 is a circuit diagram according to the present invention, FIG. 4 is an image head layout of the present invention, and FIG. 5 is an image head layout of the present invention.

Claims (1)

캡스턴 모터 제어계(가)와 영상 헤드등을 포함하는 수동 트래킹 방식의 VCR에 있어서, 영상 헤드(9)와 자동 트래킹용 영상 헤드(12)의 출력을 각각 증폭기를 거쳐 피크 검출기(10)(13)에 인가되고, 피크 검출기(10)(13)의 출력은 차동 증폭기(11)에 인가되어 영상 헤드(9)(12)로부터의 신호의 차이에 따른 출력이 차동 증폭기(11)로부터 출력되며, 이 신호는 샘플.홀드기(15)와 증폭기(Amplo)를 거친후 스위치(SW1)를 통해 캡스턴모터 제어계(가)의 가산기(A1)에 인가되어 재생시 테이프 이송 속도의 위상이 보정되게 하고, 상기 스위치(SW1)는 녹화나 재생에 대해 캡스턴 모터 제어계(가)의 캡스턴 위상 비교기(3)나 증폭기(Amplo)로 각각 절환되게 하고, 상기 차동 트래킹용 영상 헤드(21)는 재생기 영상 헤드(23)가 스캔하는 트랙의 인접트랙에서 영상 헤드(23)가 그리는 궤적과 동일한 궤적을 갖도록 드럼(18)상에 있어서 영상 헤드(19)와 각 α를 갖고 트랙의 기준면으로부터 β만큼 떨어지도록 하여 재생시 영상 헤드(23)가 최적의 상태로 스캔을 행하도록 구성한 것을 특징으로 하는 VCR의 자동 트래킹 장치.In a passive tracking VCR including a capstan motor control system (A) and an image head, a peak detector (10) (13) through an output of an image head (9) and an automatic tracking image head (12) through an amplifier, respectively. The output of the peak detectors 10 and 13 is applied to the differential amplifier 11 so that the output according to the difference of the signals from the image heads 9 and 12 is output from the differential amplifier 11. The signal is applied to the adder A 1 of the capstan motor control system A through the switch SW 1 after passing through the sample and hold unit 15 and the amplifier, so that the phase of the tape feed rate is corrected during reproduction. The switch SW 1 switches the capstan phase comparator 3 or the amplifier Amplo of the capstan motor control system for recording or playback, respectively, and the differential tracking image head 21 is a player image head. The trajectory that the image head 23 draws in the adjacent track of the track that 23 scans. The image head 23 has an angle α and an angle α on the drum 18 so as to be separated from the reference plane of the track by β so that the image head 23 scans at an optimal state during reproduction. VCR auto tracking device. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
