    • There is disclosed an optical information recording medium having phase-change recording films whose the transmittance can be made substantially uniform irrespective of the presence or absence of recording. There are also disclosed methods for recording, reading, and erasing information well at a high density on such a medium. Each of the phase-change recording films other than the top one has a phase-change recording film for recording and erasing information by a phase change caused by illumination of laser light. A transparent upper protective film is formed on the phase-change recording film to protect the phase-change recording film mainly against thermal deformation during recording and erasing of information. A transparent lower protective film is formed under the phase-change recording film to protect the phase-change recording film mainly against thermal deformation during recording and erasing of information. A foundation interference film is formed under the transparent lower protective film to adjust the transmittance of the phase-change recording film for the laser light.
    • 公开了一种具有相变记录膜的光学信息记录介质,其透射率可以基本上均匀,而不管记录是否存在。 还公开了在这种介质上高密度地记录,读取和擦除信息的方法。 除了顶部之外的每个相变记录膜具有用于通过由激光的照明引起的相位变化来记录和擦除信息的相变记录膜。 在相变记录膜上形成透明的上保护膜,以在记录和擦除信息期间主要防止相变记录膜的热变形。 在相变记录膜下面形成透明的下保护膜,以在记录和擦除信息期间主要防止相变记录膜的热变形。 在透明下保护膜下方形成基础干涉膜,以调节激光用相变记录膜的透射率。

    • For use in recording information by an irradiation of a laser beam, an optical information recording medium comprises a substrate transparent for the laser beam and a first and a second magneto-optical layer which are made of GdFeTi and TbFeCo, respectively. The first magneto-optical layer is between the substrate and the second magneto-optical layer and thermally coupled to the second magneto-optical layer. For carrying out a recording operation, the laser beam is irradiated to the substrate to heat the first magneto-optical layer. A temperature of the first magneto-optical layer is transferred to the second magneto-optical layer. In this condition, the second magneto-optical layer is subjected to a magnetic field representative of information. As a result, the information is recorded as recorded information to the second magneto-optical layer. The recorded information is transferred from the second magneto-optical layer to the first magneto-optical layer with decreasing of the temperature of the first magneto-optical layer. The recorded information can be read from the first magneto-optical layer in the manner known in the art.
    • 为了通过照射激光来记录信息,光信息记录介质包括分别由GdFeTi和TbFeCo制成的激光束透明的基板和第一和第二磁光层。 第一磁光层位于衬底和第二磁光层之间并热耦合到第二磁光层。 为了进行记录操作,激光束照射到基板上以加热第一磁光层。 第一磁光层的温度被传送到第二磁光层。 在这种情况下,第二磁光层经受代表信息的磁场。 结果,将信息作为记录信息记录到第二磁光层。 随着第一磁光层的温度的降低,所记录的信息从第二磁光层传送到第一磁光层。 可以以本领域已知的方式从第一磁光层读取所记录的信息。
