摘要： When a wavelength of a first laser beam with which a first recording medium including a first recording layer is recorded and reproduced is indicated as λ1 (nm), a wavelength of a second laser beam with which a second recording medium including a second recording layer is recorded and reproduced as λ2 (nm), the relationship between the wavelength λ1 and the wavelength λ2 is set to be expressed by 10≦|λ1−λ2|≦120. The first recording layer has a light absorptance ratio of at least 1.0 with respect to the wavelength λ1. The light transmittance of the first recording medium with respect to the wavelength λ2 is set to be at least 30 in both the cases where the recording layer is in a crystal state and in an amorphous state. In order to record and reproduce the optical multilayer disk with the above-mentioned characteristics, a multiwavelength light source with the following configuration is used. Wavelengths of fundamental waves with different wavelengths from injection parts formed at one end of a plurality of optical waveguides, which satisfy phase matching conditions different from one another and are formed in the vicinity of the surface of a substrate, are converted simultaneously, and the first and second laser beams are emitted from emission parts formed at substantially the same position at the other end of the optical waveguides. This enables an optimum optical system for high density recording and reproduction to be obtained.
摘要翻译：当记录和再现包括第一记录层的第一记录介质的第一激光束的波长被指示为λ1（nm）时，包括第二记录层的第二记录介质的第二激光束的波长为记录和再现为λ2（nm），波长λ1和波长λ2之间的关系被设置为由10≤λ1-λ2 |≤120表示。第一记录层相对于波长λ1具有至少1.0的光吸收率。在记录层处于结晶状态和非晶状态的情况下，第一记录介质相对于波长λ2的透光率被设定为至少30。为了记录和再现具有上述特性的光学多层盘，使用具有以下构造的多波长光源。同时转换与形成在多个光波导的一端的注入部分不同的波长的波长的波长，其满足彼此不同并且形成在基板表面附近的相位匹配条件，并且第一并且第二激光束从形成在光波导的另一端处的基本相同位置处的发射部分发射。这使得能够获得用于高密度记录和再现的最佳光学系统。

摘要： An information recording medium includes at least a recording layer formed on a substrate, the recording layer including a phase change layer in which a reversible phase change is caused between a crystalline state and an amorphous state by irradiation of a light beam, and a crystallization-ability improving layer for improving a crystallization ability of the phase change layer. The crystallization-ability improving layer is formed before the phase change layer is formed. Thus, crystal nucleus generation and crystal growth are caused during formation of the phase change layer, so that at least a portion of the phase change layer 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.
