摘要： An optical disk storing write-once information usable for protecting the copyright of the software by preventing the duplication, unauthorized use, etc., of the software. In the optical disk, a recording layer (213) is formed on a disk substrate (211) with a dielectric layer (212) inbetween. Then, an intermediate dielectric layer (214) and a reflecting layer (215) are successively laminated upon the recording layer (213), and an overcoat layer (216) is formed on the surface of the reflecting layer (215). A plurality of BCA (one of write-once identification information systems) sections (220a and 220b) are recorded by lowering the vertical magnetic anisotropy of the recording layer (213). At the time of reproduction, the write-once information is detected from differential signals.

摘要： Vertical magnetic anisotropy of a recording layer (15) becomes lower, depending on the composition of the recording layer and a film forming method. In such a case, it is difficult to form microscopic recording magnetic domains with stability and there is a possibility of failure to obtain a sufficiently high recording density and transfer rate in magneto-optical recording.
A magneto-optical medium with a recording layer (15) having a plurality of columns extending in a lamination direction, and a reproduction layer (13) which is placed below the recording layer and which functions as a nucleus for the columns.-

摘要： An optical disk comprising a magnetic recording layer may be used to protect software copyright by preventing the duplication, unauthorised use, etc., of the software. Write-once information is formed on the optical disk by first recording areas and second recording areas in a predetermined portion of the recording layer. The recording layers have different magnetic anisotropies in a direction perpendicular to a surface of the magnetic layer.
In a method and apparatus for reproducing write-once information from an optical disk, linearly polarised laser light is irradiated onto the predetermined portion of an optical disk and a change in polarisation orientation of light transmitted or reflected from the optical disk is detected in accordance with the recording signal on the optical disk, allowing write-once information to be reproduced from the optical disk.摘要翻译： 一种光盘，包括一个磁性记录层可用于通过防止软件的复制，未经授权使用，等等，来保护软件的版权。 一次写入信息是由在记录层的预定部分的第一记录区域和第二记录区域的光盘上形成的。 所述记录层具有沿垂直于所述磁性层的一个表面的不同的磁各向异性。 在用于再现来自光盘上写一次信息的方法和装置，线偏振激光照射到光盘的预定部分和在光反式mitted偏振方向的变化或反射来自光盘是 在与光盘上的记录信号雅舞蹈检测，一次写入允许从光盘再现的信息。
