Abstract

본 발명은 광 디스크 체인저 시스템에서의 디스크 확인 방법에 관한 것으로, (a)각각의 트레이에 디스크가 로딩되었는지를 검출하는 단계와, (b) 단계 (a)에서 검출된 각각의 디스크의 TOC(table of content) 정보를 판독하여 저장하는 단계와, (c)소정의 키 신호가 입력되면 그 키신호가 디스크 확인을 위한 디스크 확인 키신호인지를 판별하는 단계와, (d)단계 (c)에서 입력된 키신호가 디스크 확인 키신호가 아니면 그 키신호에 따른 기능을 수행하고, 디스크 확인 키 신호이면 상기 단계(b)에서 저장된 TOC데이타를 참조하여 각각의 디스크가 로딩된 트레이 번호 및 그 트레이에 로딩된 디스크의 첫번째 트랙의 재생 시간을 문자로써 디스플레이하는 단계를 포함하고 구성된다.The present invention relates to a disc identification method in an optical disc changer system, comprising the steps of (a) detecting whether a disc is loaded in each tray, and (b) detecting the TOC (table) of each disc in step (a). reading and storing the information, (c) when a predetermined key signal is input, determining whether the key signal is a disc confirmation key signal for disc confirmation, and (d) input in step (c) If the received key signal is not the disc confirmation key signal, it performs a function according to the key signal. If the disc signal is the key confirmation key signal, the tray number of each disc is loaded with reference to the TOC data stored in the step (b) and the disc is loaded in the tray. And displaying, as characters, the playing time of the first track of the recorded disc.

따라서, 본 발명은 광 디스크 체인저 시스템에서 각각의 트레이에 로딩된 디스크를 확인하고자할 때 디스크트레이를 열고 디스크를 꺼내지 않고도 몇번 트레이에 어떤 디스크가 로딩되었는지 알 수 있는 장점이 있다.Therefore, the present invention has the advantage of knowing which disk is loaded in the tray several times without opening the disk tray and removing the disk when checking the disk loaded in each tray in the optical disk changer system.

Claims

In an optical disc changer system for checking the type of each disc loaded in a disc tray in an optical disc changer system in which a plurality of discs are loaded in each tray to sequentially or selectively perform a predetermined function. (a) detecting whether a disc is loaded in each tray; (b) reading and storing table of content (TOC) information of each disc detected in step (a); (c) when a predetermined key signal is input, determining whether the key signal is a disc confirmation key signal for disc confirmation; (d) if the key signal input in step (c) is not a disc confirmation key signal; It performs the function according to the key signal, and if it is the disc confirmation key signal, it refers to the TOC data stored in the step (b) by character, the tray number of each disc loaded and the playing time of the first track of the disc loaded in the tray. A disk identification method of an optical disc changer system comprising the step of displaying.
