Abstract
An information recording medium (1) of the present invention is an information recording medium allowing information to be recorded thereon by irradiation with a laser beam or by application of electrical energy. The information recording medium (1) includes a recording layer (15) capable of undergoing a phase change by the irradiation with the laser beam or by the application of the electrical energy. The recording layer (15) contains Sb, Te, Ge, and C, and a content of Te in the recording layer (15) is at least 8 atom % but not more than 25 atom %.
