An information recording medium (100) of the present invention is an information recording medium that allows information to be recorded thereon by being irradiated with an optical beam or by being applied with electrical energy, and includes at least a recording layer (115) whose phase can change. The recording layer (115) contains antimony (Sb), carbon (C), and a light element (L) having an atomic weight of less than 33. The light element (L) preferably is at least one element selected from B, N, O, Mg, Al, and S. For example, the recording layer (115) may be composed of a material represented by a composition Sb100-x-yCxLy, where the subscripts 100-x-y, x, and y denote composition ratios of Sb, C, and the L in atomic percentage, respectively, and x and y satisfy x+y≦50.
An information recording medium that allows information to be recorded thereon by being irradiated with an optical beam or by being applied with electrical energy, the information recording medium comprising at least a recording layer whose phase can change, wherein the recording layer consists of antimony (Sb), carbon (C), and a light element (L) having an atomic weight of less than 33.
A method for producing an information recording medium, comprising at least the step of forming a recording layer consisting of antimony (Sb), carbon (C), and a light element (L) having an atomic weight of less than 33,
A sputtering target for forming a recording layer consisting of antimony (Sb), carbon (C), and a light element (L) having an atomic weight of less than 33,
A sputtering target for forming a recording layer consisting of a material that consists of antimony (Sb), carbon (C), and a light element (L) having an atomic weight of less than 33 and is represented by formula (1):
