Optical recording media and process for preparing same.

摘要

Optical recording media disclosed herein comprise a substrate and a recording layer formed thereon, wherein the recording layer comprises Te and Cr and contains 0.1 to 10 atom% of Cr based on the total of the atoms constituting the recording layer. The optical recording media are prepared by forming the recording layer comprising Te and Cr on the substrate and heat treating the thus formed recording layer. Oxidation resistance of said recording layer is improved and accordingly the optical recording medium has a prolonged life. The recording layer also has excellent recording sensitivity, notwithstanding its improved durability.
