    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.

    摘要： An optical information recording medium contains at least an optical reflective layer, an optical recording layer, a protective layer, and an optical transparency layer formed in this order on a main surface of a substrate, and has a main-information area and a sub-information area that contains an optically readable mark. The mark is constituted by removing at least the optical reflective layer in a bar cord pattern and then forming a next layer in the order over the bar cord-patterned layer.
