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.

摘要: There is provided a new medium structure to record a bar code for copyright protection or the like in an optical information recording medium capable of recording and reproducing information by a laser with respect to a dye. When a laser beam 30 is irradiated and an optical disc 10 is rotation in the direction of an arrow F, the dye of a recording layer is decomposed, a mark piece MA of a bar code 20 is formed, and a substrate is deformed by heat generated by the dye decomposition. Next, the position of the laser beam 30 is shifted to a position where a part overlaps with the mark piece MA, and when the optical disc is similarly rotated in the direction of the arrow F, a mark piece MB is formed to overlap with the mark piece MA. The above processing is repeated, so that the length of a bar is sequentially lengthened, and the bar code with a length along the standard is formed.
