ABSTRACT:
An optical recording medium composed of a transparent substrate, with an organic dye-containing layer and a light reflection layer formed on the substrate in that order, which recording medium performs recording and reproducing operations by the application of light beams used for the recording and reproducing operations respectively to the side of the transparent substrate, the organic dye-containing layer showing a light absorption ratio of 20% or more with respect to a light beam with a wavelength of 500 to 750 nm used in a recording operation, and showing a light absorption ratio of 20% or less with respect to a light beam with a wavelength of 760 to 830 nm used in a reproducing operation. In addition, the method of recording and reproducing information using the above-mentioned optical recording medium.
