Description

ABSTRACT:
An optical recording medium and methods of manufacturing the same are disclosed. The optical recording medium is provided with a transparent adhesive layer containing organic compounds such as hydrocarbon or the like that constitute resin materials, and metallic compounds whose thermal expansion coefficients are nearly equal to those of inorganic transparent materials that constitute a transparent protective layer, whereby peel-off phenomena to be caused by secular variation can be avoided.
