Abstract
본 발명의 광디스크는 기판 위에 사용자가 정보를 기록하기 위한 데이타층과, 디스크의 절대위치를 프리포맷 시키기 위한 어드래스층을 적층시켜 반복 기록 재생할 수 있도록 구성하며, 상기 데이타층과 어드레스층을 렌즈계를 통해 이중촛점으로 각각 읽어내도록 함으로써 사용자가 쓸 수 있는 데이타 영역이 중가하며, 어드레스 및 정보신호간의 크로스토크를 줄이고 트랙피치를 축소시켜 기록밀도를 향상시킬 수 있을 뿐만 아니라 디스크의 데이타층을 2층으로 제작하는 경우 재생전용 디스크와 호환할 수 있는 효과가 있다.The optical disk of the present invention is constructed so that a data layer for recording information on a substrate and an address layer for preformatting the absolute position of the disk can be repeatedly recorded and reproduced on a substrate. By reading the data in double focus, the data area that can be written by the user increases, and crosstalk between address and information signals can be reduced, and the track pitch can be reduced to improve the recording density. When produced, the effect is compatible with the disc for playback.
