摘要： PROBLEM TO BE SOLVED: To provide a recording medium in which protection of the contents of the medium is provided even though total data of the recording medium and the recording medium itself are copied and to provide a recording medium writing device, a recording medium reading device, a recording medium writing method and a recording medium reading method. SOLUTION: Embedded ownership data are made by embedding decoding key data which are used to decode ciphered contents into ownership data that are the object of proprietary rights. The embedded ownership data are recorded onto a recording medium. Since the decoding key data are embedded into the ownership data, it is difficult to separate and to take out the decoding key data from the ownership data. When copying or the like is conducted for the ownership data, the copy of the ownership data or the like can be legally pursued. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：为了提供一种记录介质，其中，即使复制了记录介质和记录介质本身的总数据，也提供了介质内容的保护，并且提供记录介质写入装置，记录介质读取装置，记录介质写入方法和记录介质读取方法。
解决方案：嵌入式所有权数据是通过嵌入用于将加密内容解码为作为所有权的对象的所有权数据的解码密钥数据进行的。嵌入的所有权数据被记录在记录介质上。由于解码密钥数据被嵌入到所有权数据中，因此难以从所有权数据中分离和取出解码密钥数据。当对所有权数据进行复制等时，可以合法追求所有权数据的副本等。版权所有（C）2005，JPO＆NCIPI
