Abstract
본 발명은 두개의 광픽업장치를 이용하여 하나의 디스크에 영상신호를 기록하거나 재생하는 기술에 관한 것으로, 종래의 디브이디 블레이어에 있어서는 두개의 기록층을 가진 디스크를 재생하거나 기록할때에도 단지 하나의 광픽업장치를 이용하게 되므로 그 만큼 데이타를 재생하거나 기록하는 속도가 느리고, 재생 동작과 기록동작을 동시에 실행할 수 없어 사용자에게 보다 다양한 서비스를 제공하지 못하게 되는 결함으로 대두되었다.The present invention relates to a technique for recording or reproducing an image signal on a disc by using two optical pickup devices. In the conventional DVD bladder, only one optical disc is used when reproducing or recording a disc having two recording layers. As the pickup device is used, the speed of reproducing or recording the data is slow, and the reproducing and recording operations cannot be executed at the same time. Therefore, the user cannot provide more various services to the user.
따라서, 본 발명은 이를 해결하기 위하여, 두 개 이상의 층을 구비한 다층 디스크를 대상으로 하여 서로 독립적으로 영상 또는 음성데이타를 리드하거나 라이트하는 제1광픽업장치 및 제2광픽업장치를 구비하고, 상기 제1,2광픽업장치를 통해 리드/라이트되는 신호를 처리하는 신호 처리수단을 구비하며, 상기 제1,2광픽업장치의 구동모드를 제어하고 상기 신호 처리수단의 동작을 제어하는 제어수단을 포함하여 구성한 것이다.Accordingly, in order to solve this problem, the present invention includes a first optical pickup device and a second optical pickup device for reading or writing video or audio data independently of each other with respect to a multilayer disk having two or more layers, Control means for processing a signal read / write through the first and second optical pickup devices, the control means for controlling a driving mode of the first and second optical pickup devices and controlling an operation of the signal processing means; It is configured to include.
