摘要： To provide a disk contents management method and a disk that are capable of preventing complete copying of contents data to be protected to achieve the protection of the copyright of contents data.
Contents data is stored on a disk with a part of the contents data being missing, and the original data corresponding to the missing part is stored on a data memory provided on an electronic circuit mounted on the disk, or a memory on a server side that is connected through a network. When reproducing the disk, the original data corresponding to the missing part, stored on the data memory or server memory, is read out as complementary data. The missing part of the contents data read out from the disk is complemented with the complementary data.

摘要： There is provided a disk/disk drive management system that is capable of setting limits to reproduction of a disk and a disk drive used for the disk reproduction, for example, setting limits to reproduction of a rental disk to prevent unrestricted copying.
On a first storage region of a disk having optical information written thereto and a second storage region of the disk having an electronic circuit 11 mounted thereon, a plurality of arbitrary codes (A001 to A999) assigned uniquely to the disk are stored. When the disk is loaded into a disk drive 1, the plurality of codes are read in and written to a code memory 114 of the electronic circuit 11, and an unused code of the plurality of codes is written to a memory 14 provided in the disk drive 1 and/or to a management memory 115 provided on the electronic circuit 11. The disk drive information that was used or is being used, user information, and other information can also be written to the management memory 115. The reproduction of the disk, and the disk drive used for the disk reproduction, are controlled based on the information written to the memory 14 or management memory 115.
摘要翻译：提供了能够对用于盘再现的盘和盘驱动器的再现设置限制的盘/盘驱动器管理系统，例如，限制了租赁盘的再现以防止不受限制的复制。在具有写入光信息的盘的第一存储区域和安装有电子电路11的盘的第二存储区域中，存储唯一分配给盘的多个任意代码（A001至A999）。当磁盘被加载到磁盘驱动器1中时，将多个代码读入并写入电子电路11的代码存储器114，并且将多个代码的未使用代码写入设置在盘中的存储器14 驱动器1和/或设置在电子电路11上的管理存储器115.也可以将使用或正在使用的磁盘驱动器信息，用户信息和其他信息写入管理存储器115.磁盘的再现，并且用于盘再现的盘驱动器基于写入存储器14或管理存储器115的信息进行控制。
