Abstract

본 발명은 하나의 디스크에 기록된 신호를 다수의 픽업을 사용하여 읽은 후 재생처리하는 다픽업 광디스크 재생 장치에 관한 것으로 광디스크로부터 기록된 정보를 독출하는 적어도 두 개 이상의 픽업과 픽업들을 제어하고 각각의 픽업들이 독출한 재생신호로부터 원래의 정보를 재생하거나 혼합된 정보를 출력하는 디스크 재생장치를 구비한다.The present invention relates to a multi-up optical disc reproducing apparatus which reads a signal recorded on one disc by using a plurality of pickups and reproduces the same. The present invention relates to at least two pickups and pickups for reading information recorded from an optical disc, respectively. And a disc reproducing apparatus for reproducing original information or outputting mixed information from a reproduction signal read out by pickups.
