Abstract

광정보를 저장하는 광 디스크 기록 매체를 개시한다. 본 발명은, 상면에 랜드와 그루우브가 교대로 형성된 기판을 구비하여 된 광 디스크 기록 매체에 관한 것으로, 상기 랜드와 그루우브에, 기록 및 소거가 가능한 제1기록영역과, 물리적인 피트에 의한 재생전용의 제2기록영역이 선택적으로 각각 형성된 것에 그 특징이 있으며, 이는 한 디스크 내에서 재생 전용영역과 기록 및 소거 전용영역으로 분리하여 분리되므로 사용이 간편하고 가격이 상대적으로 저렴하다.An optical disk recording medium for storing optical information is disclosed. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk recording medium having a substrate having lands and grooves alternately formed on an upper surface thereof, wherein the lands and grooves include a first recording area capable of recording and erasing, and a physical pit. The second recording area exclusively for reproduction is formed separately, which is easy to use and relatively inexpensive since it is divided into a reproduction only area and a recording and erasing area in one disc.
