Abstract

본 발명은 복수의 음악정보가 수록된 컴팩트디스크에서 선호하는 음악의 트랙번호를 저장하기 위해 해당 특정채널의 모드데이터에 포함된 곡번(트랙번호)를 해당 컴팩트디스크의 ID데이터로 하여 시스크재생시스템에 저장하고 그 디스크재생시스템에 컴팩트디스크가 장착되면 ID데이터의 등록여부를 판단하여 등록된 컴팩트디스크인 경우에는 미리 등록된 곡번을 재생하도록 컴팩트디스크의 선곡제어장치에 관한 것으로, 프로그램영역에 기록된 서브코드를 갖는 컴팩트디스크에서 독취된 RF신호를 증폭 및 파형처리하고 EFM복조된 신호로부터 해당 컴팩트디스크의 서브코드를 재생하는 서브코드재생부(24)와, 상기 프로그램영역에 기록된 서브코드를 갖는 컴팩트디스크에 대한 선곡등록모드의 설정과 해당 컴팩디스크의 곡목을 선곡등록하기 위한 재생데이터선택부(26), 상기 재생데이터선택수단(26)에 의해 선곡재생데이터가 설정되면 상기 서브코드재생수단(24)에 의해 재생되는 상기 컴팩트디스크의 서브코드에 포함된 소정채널의 모드데이터를 해당 컴팩디스크의 식별데이터로서 등록되도록 함과 더불어 그 서브코드에 포함된 곡번을 저장하고 재생모드에서 재생대상으로 되는 컴팩트디스크의 디스크정보를 독취하여 미리 등록된 식별데이터와 동일한 경우 미리 등록된 곡번의 재생이 수행되도록 하는 제어부(28), 그 제어부(28)의 제어하에 해당 컴팩트디스크의 식별데이터와 곡번을 재생예약데이터로서 등록하는 재생데이터예약등록부(30)및, 상기 재생데이타선택부(26)에 의해 식별데이타가 등록된 컴팩트디스크의 장착시 해당 컴팩트디스크의 예약된 선곡위치를 재생하도록 하는 디스크서보 메카니즘(32)을 포함하여 구성된 것이다.According to the present invention, in order to store a track number of a preferred music in a compact disc in which a plurality of pieces of music information is recorded, the track number (track number) included in the mode data of the specific channel is used as the ID data of the compact disc. When the compact disc is stored in the disc reproducing system, the ID data is judged to be registered. In the case of the registered compact disc, the selection control device of the compact disc is used to play the pre-registered song number. A subcode reproducing unit 24 for amplifying and waveform-processing the RF signal read from the compact disc having the code and reproducing the subcode of the compact disc from the EFM demodulated signal, and the compact having the subcode recorded in the program area. Setting of the song selection mode for the disc and resetting to register the song title of the compact disc. When the music selection playback data is set by the raw data selection section 26 and the playback data selection means 26, the mode data of a predetermined channel included in the sub code of the compact disc reproduced by the sub code playback means 24. Is registered as identification data of the corresponding compact disc, and the song number included in the subcode is stored, and the disc information of the compact disc to be played back is read in the playback mode, and if the same as the previously registered identification data, the previously registered song A control unit 28 for performing reproduction reproduction, a reproduction data reservation registration unit 30 for registering identification data and a song number of the compact disc as reproduction reservation data under the control of the control unit 28, and the reproduction data selection unit 26; When the compact disc registered with the identification data is installed, the disc servo menu to play the reserved selection position of the compact disc It comprises a mechanism (32).
