Abstract

본 발명은 CD(compact disk)의 재생 방법에 관한 것으로서, 특히 TOC(table of content)가 없는 CD의 재생 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of reproducing a compact disc (CD), and more particularly, to a method of reproducing a CD without a TOC (table of contents).

무단 복제를 방지하는 TOC가 없는 CD의 재생 제어 방법은, TOC가 리드되어지는가를 확인하는 과정; 상기 확인과정에서 TOC가 리드되지 않으면 소정의 트랙을 이동하여 리드하는 과정; 상기 리드과정에서 리드된 데이터가 TOC가 없는 디스크에서 리드되었는지를 확인하는 과정; 상기 확인 과정에서 TOC가 없는 디스크이면 새로운 포맷으로 리드하고 리드인(lead in) 영역의 데이터이면 일반 CD 포맷으로 리드하는 과정을 포함함을 특징으로 한다.A playback control method for a CD that does not have TOC preventing unauthorized copying includes a process of confirming whether TOC is read; If the TOC is not read in the checking process, moving a predetermined track and reading the track; Confirming whether the read data in the read process is read from the disk without the TOC; If the disc does not have a TOC in the checking process, the disc is read in a new format, and if it is a lead in area, the disc is read in a general CD format.

상술한 바와 같이 본 발명에 따른 TOC가 없는 CD 재생 제어 방법은 무단 복제가 불가능한 TOC가 없는 CD를 재생할 수 있고 일반 CD의 포맷을 재생하는 기능을 제공한다.As described above, the TOC-free CD playback control method according to the present invention provides a function of playing back a CD without a TOC that can not be copied without permission and reproducing a format of a general CD.
