摘要： An information recording medium (50) includes at least a recording layer (5) formed on a substrate (1), the recording layer (5) including a phase change layer (4) in which a reversible phase change is caused between a crystalline state and an amorphous state by irradiation of a light beam (27), and a crystallization-ability improving layer (3) for improving a crystallization ability of the phase change layer. The crystallization-ability improving layer (3) is formed before the phase change layer (4) is formed. Thus, crystal nucleus generation and crystal growth are caused during formation of the phase change layer (4), so that at least a portion of the phase change layer (4) is in the crystalline phase after the formation. Thus, information signals can be recorded/reproduced at a high density and a high linear velocity, and thus the present invention provides a highly reliable optical information recording medium. Further, the present invention provides an information recording medium that allows a recording operation to be performed on the recording layer in the as-depo amorphous state without the initialization process.

摘要： An information recording medium (50) includes at least a recording layer (5) formed on a substrate (1), the recording layer (5) including a phase change layer (4) in which a reversible phase change is caused between a crystalline state and an amorphous state by irradiation of a light beam (27), and a crystallization-ability improving layer (3) for improving a crystallization ability of the phase change layer. The crystallization-ability improving layer (3) is formed of a halogenide and before the phase change layer (4) is formed. Thus, crystal nucleus generation and crystal growth are caused during formation of the phase change layer (4), so that at least a portion of the phase change layer (4) is in the crystalline phase after the formation. Thus, information signals can be recorded/reproduced at a high density and a high linear velocity, and thus the present invention provides a highly reliable optical information recording medium. Further, the present invention provides an information recording medium that allows a recording operation to be performed on the recording layer in the as-depo amorphous state without the initialization process.

Of the upper protective layer, the intermediate layer and the reflective layer, the heat conductivity of the layer (4) closest to the recording layer is the smallest of the three layers, and heat conductivities of the others of the three layers increase with increasing distance from the recording layer, and the thickness of the recording layer is from 4nm to 16nm.
