摘要： An optical information recording medium has at least an optical reflective layer, an optical recording layer, an protective layer, and an optical transparency layer formed in that order on the main surface of a disc-shaped substrate. An area in which the protective layer is formed is made wider than an area in which the reflective layer is formed, and made narrower than an area in which the optical transparency layer is formed.

摘要： An optical information recording medium that has satisfactory main information recording characteristics and in which burst cutting area (BCA) marks can be formed without damaging a protective layer or a light-transmitting layer is provided. In forming the light-reflecting layer by vapor deposition, sputtering, ion-plating, or the like, part of the region is masked so as to make the thickness and/or material of the light-reflecting layer in a main information recording region where main information is recorded different from that of the light-reflecting layer in a BCA equivalent region. As a result, burst cutting of the light-reflecting layer in the BCA equivalent region becomes easier than in the main information recording region.
