ABSTRACT:
An optical recording medium includes a substrate having light transmission properties, which has laminated on a main surface thereof a recording layer and a metal reflection layer. The recording layer is made of a compounded organic dye thin film which contains a specified aromatic amine compound in an amount of not smaller than 3% by weight but below 30% by weight based on the total weight of the recording layer and a specified asymmetric cyanine dye having absorption to light having a wavelength of 500 to 700 nm in an amount of not smaller than 30% by weight but below 97% by weight based on the total weight of the recording layer. The recording layer is applicable to a short-wavelength (500 to 700 nm) semiconductor laser so that an optical recording medium according to the DVD-ROM standards having excellent stability of the dye film and allowing a decrease in jitter component upon high density recording.
