The present invention is in the field of optical recording media, and is directed to an optical recording medium which comprises the following layers;

Optical recording medium based on Fabry-Perot principle

In a recordable/replayable optical recording medium having a thin metal recording layer and an optical recording method therefor, the optical recording medium includes a substrate, a thin metal film formed on the substrate, a reflective layer arranged on the thin metal film, a buffering layer interposed between the thin metal film deformed by heat, and a protecting layer for protecting the deposited layers. Recording is facilitated by adopting a buffering layer and compatibility with conventional CD players is possible. Since expensive organic dyes are not necessary, manufacturing costs can be reduced and productivity can be greatly improved.

Recordable/replayable optical recording medium and optical recording

Disclosed is an organic optical recording medium comprising a substrate, a recording layer on the substrate, a reflective layer and protective layer disposed on the recording layer, wherein the recording layer has a refractive index of 1.7 or less and includes an organic dye and a mixture of two or more polymers having different thermal properties and compatibilities from an ambient temperature to 80.degree. C. The organic optical recording medium of the present invention has improved recording characteristics and good processability and is inexpensive.
