Abstract
본 발명은 광디스크에 관한 것으로, 광디스크 기판의 랜드영역과 그루브 영역중의 어느 한 영역을 재생전용 광디스크와 같이 기판에 흠을 새겨 넣어 정보를 기록하여 재생전용부로 이용하고, 다른 한부분은 광자기 디스크와 같이 기록 및 소거, 재생이 가능한 소거 가능형으로 이용함으로써 광디스크의 기록밀도를 2배로 증가시킴과 아울러 하나의 광디스크로 2가지 기능이 가능하게 된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disc, wherein any one of the land area and the groove area of the optical disc substrate is used as a reproducing unit by recording information by stamping the substrate like a reproducing optical disc, and the other part is an optical magnetic disc. By using the erasable type capable of recording, erasing, and reproducing as described above, the recording density of the optical disc is doubled and two functions are possible with one optical disc.
