    • The object of the present invention is to provide a multilayer phase-change information recording medium comprises a substrate, and N layers of information layer (N represents an integral number of 2 or more), and each of the information layers comprises at least a recording layer in which information is recorded by irradiating laser beam to induce a phase change between crystalline phase and amorphous phase. The present invention is characterized in that when the information layer is disposed so that a first information layer, a second information layer, a third information layer . . . , and N information layer are disposed in this sequence from the laser beam irradiation side, at least one information layer other than the N information layer comprises a lower protective layer, a recording layer, an upper protective layer, a reflective layer, and a thermal diffusion layer disposed in this sequence is from the laser beam irradiation side; the thermal diffusion layer comprises at least indium (In) and oxygen (O) and further comprises any one of titanium (Ti) and zirconia (Zr); and the atomic ratio of indium (In) to all the metal elements in the thermal diffusion layer, In/all the metal elements, is 0.75 to 0.9.
    • 本发明的目的是提供一种包括衬底和N层信息层(N表示2个或更多个的整数)的多层相变信息记录介质,并且每个信息层至少包括记录 其中通过照射激光束来记录信息以诱导结晶相和非晶相之间的相变。 本发明的特征在于,当信息层被布置为使得第一信息层,第二信息层,第三信息层被布置时。 。 。 和N信息层按照该顺序从激光束照射侧配置,除了N信息层以外的至少一个信息层包括下保护层,记录层,上保护层,反射层和热 以该顺序设置的扩散层来自激光束照射侧; 所述热扩散层至少包含铟(In)和氧(O),并且还包含钛(Ti)和氧化锆(Zr)中的任一种。 并且铟(In)与热扩散层中的全部金属元素In /所有金属元素的原子比为0.75〜0.9。
