Abstract

본 발명은 디스크의 기록 정보 검색 장치에 관한 것으로, 종래에는 일정한 회전 속도를 유지하는 디스크 검색 시스템의 경우 디스크의 외곽측으로 갈수록 기록 밀도가 적어지므로 정보 저장량의 손실이 발생하는 문제점이 있고 또한, 회전 속도를 가변하여 디스크의 중심측과 외곽측의 각 속도를 항상 일정하게 유지하는 디스크 검색 시스템의 경우 기록 밀도의 손실은 없으나 회전 속도를 변화시키는데 필요한 엑세스 시간이 길어지는 문제점이 있었다. 이러한 종래의 문제점을 개선하기 위하여 본 발명은 디스크의 위치에 상관없이 일정한 밀도로 정보를 기록하고 검색시 디스크의 회전 속도를 변경함이 없이 신호 처리 속도를 기록 위치에 따라 가변시키므로써 정보 검색 시간을 단축할 수 있도록 창안한 것으로, 본 발명은 위치에 상관없이 기록 밀도가 동일한 디스크 상의 기륵 위치에 따라 클럭을 가변하여 기록 정보를 검출하므로 디스크의 회전 속도를 변경할 필요가 없어 정보 검색 시간을 줄일 수 있다.The present invention relates to a recording information retrieval apparatus for a disc. Conventionally, in the case of a disc retrieval system that maintains a constant rotational speed, the recording density decreases toward the outer side of the disc, so that a loss of information storage amount occurs, and the rotation speed In the case of a disc retrieval system that maintains constant speeds at the center and the outside of the disc at all times, there is no loss of recording density, but the access time required to change the rotational speed is long. In order to improve this conventional problem, the present invention records information at a constant density regardless of the position of the disc, and changes the signal processing speed according to the recording position without changing the rotational speed of the disc at the time of retrieval. In order to shorten the present invention, the present invention detects recording information by varying a clock according to an existing position on a disc having the same recording density, regardless of the position, so that the information retrieval time can be reduced without changing the rotational speed of the disc. .
