    摘要： The invention allows two-photon absorption to occur in response to a short-wavelength light beam. The recording layer (101) of the optical information recording medium (100) of the invention contains, as a two-photon absorbing material, a compound represented by general formula (1) having a hexadiyne structure that includes in the center thereof two acetylene groups connected by a δ-bond. At the time of information recording where a recording mark (RM) is formed in the recording layer (101), two-photon absorption occurs in response to a condensed, short-wavelength recording light, whereby the recording mark (RM) is formed.

    摘要： A write once optical recording medium has an inorganic recording film which includes an oxide film having germanium oxide (GeO) as a principal component, and a metal film adjacent to the oxide film, the metal film having a titanium/silicon alloy (TiSi) as a principal component. According to this arrangement, it is possible to construct an inexpensive write once optical recording medium with large strength capable of high density recording by using a short wavelength light source and an optical system with a high numerical aperture having excellent characteristics.

    摘要： An optical information recording medium including a recording layer that can record a large amount of information is manufactured using a simple system. A single recording layer is formed by bonding two optically transparent substrates on which the first photosensitive polymer and the second photosensitive polymer are spread such that the layers of the photosensitive polymers face each other. Furthermore, since the absorptivity of light in the recording layer increases as the focal point of light for information recording moves in a depth direction, information can be recorded without decreasing the recording transfer rate of the information.

    摘要翻译： 使用简单的系统制造包括能够记录大量信息的记录层的光学信息记录介质。 通过粘合两个光学透明的基底来形成单一的记录层，其中第一光敏聚合物和第二光敏聚合物在其上被扩散，使得感光聚合物层彼此面对。 此外，由于记录层中的光的吸收率随着用于信息记录的光的焦点在深度方向上移动而增加，所以可以在不降低信息的记录传送速率​​的情况下记录信息。
