    • PURPOSE: To prevent an externally referenced form file consisting of only a reference information storage section from referencing an unintended file. CONSTITUTION: An optical disk 20a is loaded to an external drive 71, which copies or moves one file or more recorded in the optical disk 20a to a hard disk 72 of a personal computer 70. The personal computer 70 edits the files and again copies or moves the result of edit to the optical disk. The result of edit is the externally referenced form file to its reference information storage section of which reference file information and a specific character string generated from a disk ID are imbedded. In the case of reproducing the optical disk recording the result of edit, checking by the character string is conducted. That is, the coincidence between the character string in a file 62 of the result of edit and the character string on the basis of the disk ID read from the disk is detected. When the disk is the substantial optical disk 20a, since the both are coincident, the reproduction is permitted. However, when the disk is other optical disk 20b, since both the disk IDs are dissident, the reproduction is inhibited.
    • 目的:防止仅引用参考信息存储部分的外部参考表单文件引用非预期文件。 构成:将光盘20a装载到外部驱动器71,外部驱动器71将记录在光盘20a中的一个或多个文件复制或移动到个人计算机70的硬盘72.个人计算机70编辑文件并再次复制或复制 将编辑结果移动到光盘。 编辑结果是其参考信息存储部分的外部引用表单文件,其参考文件信息和从磁盘ID生成的特定字符串被嵌入。 在再现记录编辑结果的光盘的情况下,进行字符串的检查。 也就是说,检测编辑结果的文件62中的字符串与基于从盘读取的盘ID的字符串之间的一致性。 当盘是实质的光盘20a时,由于两者都一致,所以允许再现。 然而,当盘是其他光盘20b时,由于两个盘ID都是异常的,所以再现被禁止。
