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 telluride and a halogenide 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.
