PURPOSE:To stably obtain a signal having good weatherability, high sensitivity and good quality, by forming a recording layer from tellurium, selenium, nitrogen and at least one element selected from a group consisting of ruthenium, rhodium, osmium, iridium and platinum. CONSTITUTION:In optical recording medium having a recording layer, the recording layer is composed of tellurium, selenium nitrogen and at least one element selected from ruthenium, rhodium, osmium, iridium and platinum. By constituting the main components of the recording layer of tellirium, selenium and nitrogen, a compound of nitrogen and chalcogen elements is formed in the layer and the formation of small holes being the initial stage of hole forming recording can be performed by laser beam having relatively weak power and, therefore, an optical recording medium having good weatherability and high sensitivity and obtaining a good quality signal is obtained. By adding at least one element selected from a group consisting of ruthenium, rhodium, osmium, iridium and platinum to tellurium, selenium and nitrogen, a pit is formed without being largely expanded and a good recording and regenerating characteristic is obtained. |
