Claims (2)

서로가 다른 주파수로서 변조된 음성신호정보와 영상신호정보의 제각기를 기록시킨 두개의 트랙을 평행시켜서 나선상으로 가지고 이루어진 것을 특징으로 하는 비데오 디스크.A video disk comprising two tracks in which audio signal information and video signal information each of which are modulated at different frequencies are recorded in parallel to each other in a spiral shape. 서로가 다른 주파수로서 변조된 음성신호정보와 영상신호정보의 제각기를 기록시킨 두개의 트랙을 평행시켜 나선상으로 가지고 이루어진 비데오 디스크의 각 트랙에 올라타서 신호 픽업 매체가 트레이스 되므로서 각트랙의 기록정보를 검출하는 신호검출회로와, 이 신호검출회로의 출력에서 음성 신호정보와 영상 신호정보와를 분리하는 제1,제2의 필터회로와, 이 제1,제2의 필터회로의, 출력을 1,2를 각각 정류하여 차동증폭회로의 비교용 제1,제2의 입력단에 가하는 제1,제2의 정류회로와, 전기한 차동증폭회로의 차동출력이 제어량으로서 가하여지며 전기한 신호를 픽업 매체의 각 트랙에 대한 트래킹위치를 제어하는 랙보상장치와를 구비한 것을 특징으로 하는 디스크 재생장치.Two tracks, each recording the audio signal information and the video signal information, which are modulated at different frequencies, are recorded in parallel to each track of a video disc formed in a spiral shape, and the signal pickup medium is traced to record the track information of each track. A signal detection circuit for detecting, first and second filter circuits for separating audio signal information and video signal information from the output of the signal detection circuit, and outputs of the first and second filter circuits; The first and second rectifier circuits respectively rectified and applied to the first and second input terminals of the differential amplifier circuit and the differential outputs of the differential amplifier circuit are applied as a control amount, and the electrical signal is transferred to the pickup medium. And a rack compensator for controlling a tracking position for each track. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
