Abstract

본발명은 소거가능형 양면 유기광기록 디스크에 관한 것으로, 투명기재 양면에 기록층, 소거층 및 프리그루브가 형성된 투명층이 차례로 각각 형성되고, 프리그루브가 형성된 면에는 Cu, Al, Rh, Au, Pt중 적어도 일종으로 이루어진 반사막이 20-150Å의 두께로 적층되며, 소거층과 대응하는 프리그루브 부위와의 공간에서 트래킹되어 기록 및 재생토록 한 것으로, 프리그루브에 의해 프리포매팅되므로 트래킹 문제를 해결할 수 있고 양쪽면으로 기록가능하여 기록용량이 2배로 커지며 기판의 프리그루브면에 반사막을 형성하여 기록특성(CNR)이 우수한 특징을 가진다.The present invention relates to an erasable double-sided organic optical recording disk, wherein a transparent layer having a recording layer, an erasing layer, and a pregroove are formed on both surfaces of the transparent substrate, respectively, and on the surface on which the pregroove is formed, Cu, Al, Rh, Au, A reflective film made of at least one of Pt is stacked to a thickness of 20-150Å, tracked in the space between the erase layer and the corresponding pregroove portion, and recorded and reproduced. It is capable of recording on both sides, so that the recording capacity is doubled, and the reflective film is formed on the pregroove surface of the substrate, so that the recording characteristic (CNR) is excellent.
