PURPOSE:To provide an optical recording medium having stable performance and improved environmental resistance by successively forming a recording film, a light reflecting film and a protective film on a transparent substrate with formed grooves and regulating the depth of the grooves to 800-1,100Angstrom . CONSTITUTION:When a recording film 12 contg. a phthalocyanine coloring matter, a light reflecting film 13 and a protective film 14 are successively formed on a transparent substrate 11 with formed grooves 10 to obtain an optical recording medium 2, the depth of the grooves 10 is regulated to 800-1,100Angstrom . The grooves are easily transferred at the time of injection molding and the objective optical recording medium having stable performance by which CD-R standard is satisfied and the advantage of excellent environmental resistance can be obtd. |
