Abstract
이발명은 컴팩트 디스크의 고속 재생장치에 관한 것으로서, 컴팩트 디스크 플레이어에 메모리 제어부를 추가 구성하여, 컴팩트 디스크를 N배속으로 회전시키고 N배속으로 회전되는 컴팩트 디스크에 기록된 정보를 N배속으로 재생하여 이를 메모리 제어부에 저장하였다가, 메모리 제어부에 저장된 데이타량이 일정량 이상이되면 메모리 제어부에 저장된 데이타를 정상속도로 출력하도록 함으로써, 컴팩트 디스크 플레이어에 충격이가해져 순간적으로 컴팩트 디스크 플레이어가 동작되지 않더라도, 메모리 제어부에 저장된 데이타의 실시간정보를 이용하여 재생동작을 계속 수행할 수 있도록 하였다. 이 발명은 모든 컴팩트 디스크 플레이어에 적용가능하고, 특히 휴대용 컴팩트 디스크 플레이어나 자동차용 컴팩트 디스크 플레이어 등 외부 충격이 잦은 곳에 장착되는 컴팩트 디스크 플레이어에 매우 유용하다.The present invention relates to a high speed reproducing apparatus for a compact disc, which further comprises a memory control unit for a compact disc player, which rotates the compact disc at Nx speed, reproduces the information recorded on the compact disc rotated at Nx speed, and stores the memory. When the amount of data stored in the controller is greater than or equal to a certain amount, the controller stores the data stored in the memory controller at a normal speed so that the compact disc player is shocked and the data stored in the memory controller is not instantaneously operated. It is possible to continue the playback operation by using real-time information of. This invention is applicable to all compact disc players, and is particularly useful for compact disc players mounted in places where external shocks are frequent, such as portable compact disc players or automotive compact disc players.
