    • The present invention pertains to a vector wave recording medium which: has an information recording layer comprising a photo-induced birefringence material; irradiates a recording signal light of a first polarization state, and a recording reference light of a second polarization state that differs to the first polarization state; and carries out vector wave multiplex recording by holography on the information recording layer. The vector wave recording medium is configured in such a manner that ηmin/ηmax=0.1 is satisfied, where, assuming irradiation energy for the recording signal light and the recording reference light is constant, the maximum value of the diffraction efficiency of a playback signal light from diffraction gratings corresponding to information recorded in the information recording layer after the vector wave multiplex recording has been carried out by holography on the information recording layer, is regarded as ηmax, and the minimum value is regarded as ηmin. A vector wave recording medium and a multiplex recording and playback method therefor, which do not require scheduling to be carried out, and which carry no risk of causing a reduction in transfer rates in a recording system, can thus be provided.
    • 本发明涉及一种矢量波记录介质,其具有包含光致双折射材料的信息记录层; 照射第一偏振态的记录信号光和与第一偏振态不同的第二偏振态的记录参考光; 并通过全息记录在信息记录层上进行矢量波多重记录。 矢量波记录介质被配置为使得etamin / etamax = 0.1,其中假定记录信号光和记录参考光的照射能量恒定,则重放信号光的衍射效率的最大值 在信息记录层上通过全息术进行矢量波复用记录之后,对应于记录在信息记录层中的信息的衍射光栅被认为是etamax,最小值被认为是Etamin。 因此,可以提供不需要执行调度并且不会导致记录系统中的传送速率降低的风险的矢量波记录介质和多路记录和重放方法。
