ABSTRACT:
There is provided with an optical recording medium comprising at least a dye-containing recording layer and a reflective layer laminated on a transparent substrate in this order which has a reflectance of 65% or higher, measured through the substrate, to a light beam having a selected wavelength (.lambda.1) of from 770 to 830 nm and has a reflectance of 15% or higher to a light beam having a selected wavelength (.lambda.2) of from 630 to 690 nm and which is recordable and reproducible with a laser beam having the wavelength of .lambda.1 and being reproducible with a laser beam having the wavelength of .lambda.2. In addition, the recording layer has a dye A having the absorption maximum at the wavelength shorter than 630 nm mixed with a dye B having the absorption maximum at the wavelength of from 630 to 900 nm. Alternatively, an interference layer is provided along with the recording and reflective layers. The recording layer is based on a phthalocyanine dye while the interference layer is based on an inorganic dielectric, a polymer, or an azo dye. The requirements for the interference layer are also provided.
