Abstract

본 발명은 풀 모션 비디오기능을 갖는 대화형 디스크 플레이어(Compact Disk -Interactive/Full Motion Video : CD-I(FMV) 및 구동방법에 관한 것으로, 컴팩트 디스크를 구동하는 데크 메카니즘을 복수로 구비하여 2장 이상으로 구성된 디스크를 재생중에 교체하는 별도의 조작없이 순차적으로 재생가능 하고 하나의 응용 프로그램으로 2개의 디스크에서 데이타를 읽어내어 동시에 재생하는 것이 가능하여 사용자의 편리함을 도모하는 효과가 있다.The present invention relates to an interactive disk player having a full motion video function (Compact Disk-Interactive / Full Motion Video: CD-I (FMV)) and a driving method, comprising a plurality of deck mechanisms for driving a compact disk. The above-described discs can be sequentially played without a separate operation during playback, and data can be read from two discs at the same time by one application program and played simultaneously.
