Abstract

〔목적〕급한용무등이 발생하여 특정키로 전원 오프할때 및 잘못하여 도어 오픈해서 강제적으로 전원이 오프될때에 있어서, 재생재개시에 재생이 중단된 시점이 동작 상태에서 시작하도록 한 것이다.
〔구성〕CD-ROM디스크를 재생제어하는 프로그램의 진행 상황을 기억하는 기억수단(6)과, 전원 스위치 수단(7)과 북마커 스위치 수단(7)을 가지며,기억수단(6)은 프로그램 진황 상황을 순차적으로 기억해서, 전원 스위치수단(7)에 의해서 CD-ROM디스크의 재생제어를 정지한 때에는, 기억수단(6)의 내용을 유지하고 있지 않지만, 북마커 스위치 수단(7)에 의해 또한 뜻하지 않게 CD-ROM 디스크의 재생 제어가 중단될 때에는, 이 기억수단(6)에 의해서 프로그램의 진행 상황을 보존해서, 이 CD-ROM 디스크의 재생 제어를 재개할때 기억수단(6)의 기억 내용을 호출하는 CD-ROM 디스크의 재생제어 상태를 중단된 시점의 상태로 복원 하도록 구성한 것이다.
