<p>The optical recording media disclosed herein comprises a substrate and a recording layer formed thereon, wherein the recording layer is irradiated with beam of energy to form thereon bits corresponding to given pieces of information and thereby record the pieces of information. The recording layer comprising Te, Cr, C and H, the proportion of Cr contained in said recording layer, based on all atoms costituting the recording layer, is 0.1-40 atom% and that of C contained in said recording layer is 0.1-40 atom%. In another aspect, the proportion of Cr contained in said recording layer, based on the sum total of Te and Cr atoms present in said recording layer, is 0.1-60 atom%, and the proportion, based on the sum total of Te, Cr and C atoms present in said recording layer, of C is 0.1-40 atom%. According to the optical recording media as disclosed above, the recording layer improves in oxidation resistance and long duration of life of the optical recording media can be expected, because the recording layer comprising Te, Cr, C and H. In this connection, the distribution of C contained in the recording layer is not always uniform, and C may be distributed in the recording layer so that the content of C becomes smaller in the direction receding from the substrate side.</p> |
