Description

장시간용 정각속도 디스크 및 플레이어
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제2도는 본 발명의 정각속도 디스크. 제3도는 본 발명에 따른 회로도. 제4도는 본 발명에 따른 흐름도.

Claims (2)

  1. 디스크를 구동하기 위한 스핀들모터(70)와, 화상 및 음성 정보를 내장하고 있는 디스크(80)와, 상기 디스크(80)상에 있는 화상 및 음성 정보를 검출하기 위한 픽업부(90)와, 상기 픽업부(90)의 동작에 따른 제어신호를 공급하기 위한 픽업서보부(100)와, 상기 스핀들모터(70)의 구동 및 속도를 제어하는 스핀들모터콘트롤러(400)와, 시스템의 운용 프로그램에 따라 비교, 판단하고 랜덤 데이타를 보관하며 영상 음성신호 검출상태를 제어 처리하는 마이콤부(500)와, 화상과 음성신호를 검파하는 비디오/오디오 검파회로(700)를 구비한 비디오 디스크 플레이어 시스템에 있어서, 상기 디스크(80)상의 프레임 동기를 검파하는 디스크동기 검파회로(200)와, PLL에 의해 재생된 클럭에 의해 디스크 동기검파회로(200)에서 검출된 프레임 동기신호를 후술하는 마이콤부(500)에 설정된 데이타와 비교하는 비교기(300)와, 상기 마이콤부(500)에서 정지화면시 1회전당 2프레임이 재생되므로 화면의 떨림을 방지하기 위해 CAV 디스크(80) 트랙내 프레임 번호를 마이콤(500)에서 파악한 후 필요 없는 다른 프레임이 재생되지 않도록 하는 비디오 프레임 재생소거회로(600)와, 정지화면시 화면에서 음성신호는 제거되고 화상신호만 화상 메모리에서 억세스되도록 1/30Sec 동기 신호를 발생하는 1/30동기 발생회로(800)로 구성된 것을 특징으로 하는 장시간용 정각속도 비디오 디스크 플레이어.
  2. 정각속도 디스크에 있어서, 동기를 4개로 하여 고밀도로 기록한 것에 특징이 있는 장시간용 정각속도 비디오디스크.
