Abstract: PURPOSE:To improve mechanical characteristics and to lessen the mechanical change, such as warpage, of the optical recording medium so as to decrease the burden on a system for executing recording and reproducing by forming a dielectric layer of a composite contg. at least a chalcogen compd., oxide and carbon. CONSTITUTION:Since the dielectric layer is the composite contg. at least the chalcogen compd., the oxide and the carbon, the internal stresses of the dielectric layer are decreased. The mechanical deformation, such as warpage, of the optical recording medium is, therefore, lessened. Further, the adhesive strength to the recording layer is excellent and the generation of the peeling and cracking of the film is suppressed. Since the dielectric layer is decreased in internal stresses, the dielectric layer obviates the generation of the mechanical destruction of the dielectric layer and the peeling of the recording layer and the dielectric layer by the heat cycles of heating and cooling at the time of repetition of recording and erasing. The excellent characteristics to repeat recording and erasing are obtd.
