摘要： PROBLEM TO BE SOLVED: To perform a stable recording even by a laser beam of a low power while maintaining a high reflectance of a recording layer by adopting a compound which shows a heating reaction as an organic coloring matter, in an optical recording medium equipped with an organic coloring matter film containing the organic coloring matter as the recording layer. SOLUTION: When information is recorded on an optical disk 1, a laser beam is irradiated to a recording layer 3 from a base 2 side. Then, an organic coloring matter of the recording layer 3 at the section, to which the laser beam has been irradiated, heats and decomposes. As a result, the section, wherein the organic coloring matter has been decomposed, has a different reflectance from the other section, and a pit is formed in the recording layer 3. In this case, in the recording layer 3, an organic coloring matter, of which the decomposing reaction is a heating reaction, is contained. By this constitution, even when a laser beam of a low power is used, an insufficient heating value for the recording is compensated by a heating value generated when the organic coloring matter decomposes, and a stable recording is performed. As such an organic coloring matter, a direct dye such as a cyanine coloring matter and others are adopted.

摘要： PROBLEM TO BE SOLVED: To provide overall print having a respectable appearance, when print ing the substrate surface of a card-type CD, and to satisfy functions required of the card-type CD. SOLUTION: A drive hole 12 for centering to a drive table is formed in the center of a substrate 11 of a card-type CD 10, with a prescribed depth x from the side of a laser light irradiated face 15. An annular digital information signal pattern 14 is provided in the substrate on the side of print face 13 in the outer periphery of the drive hole 12. Since the drive hole 12 is formed only on the laser light irradiated face 15 side, a print face opposite to the irradiated face 15 is made flat throughout. Therefore, full-surface print on the print face 13 made possible, and together with restrictions on print being removed beautiful appearance is also obtained. When the effective depth x of the drive hole 12 is within the range of 0.60 to 1.15 mm, the clamp means of a current drive device can be used as it is.
