    • An optical information recording medium includes a substrate having a pregroove thereon, an optical recording layer containing a light-absorbing substance composed of a dye absorbing a laser beam, and a light-reflective layer reflecting the laser beam. The ratio of the cross-sectional area of the optical recording layer (i.e., the dye) in the pregroove to the cross-sectional area of the pregroove in the direction of the diameter of the optical information recording medium is about 30% to about 63%. In the optical information recording medium, the phenomenon by which the recording power of the laser beam heats the dye in the optical recording layer and the heat is diffused through the optical recording layer and the light-reflective layer is considered.

    • 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.
