标准范围

ISO/IEC 29121:2009提供了档案数据存储的数据迁移方法规范，允许制造商使用DVD-R（ISO/IEC 23912:2005）、DVD-RW（ISO/IEC 17342:2004）、DVD-RAM（ISO/IEC 17592:2004）和+R（ISO/IEC 17344:2006和ISO/IEC 25434:2007）的存储系统，和+RW（ISO/IEC 17341:2006和ISO/IEC 26925:2006）磁盘用于信息存储，以根据初始性能要求对磁盘寿命潜力进行分类，并允许用户监控是否持续符合驱动器/磁盘制造商确定的级别所需的错误限值。数字数据可以迁移到下一个新磁盘，而不会从当前磁盘丢失，只要在迁移之前和迁移过程中完全纠正了数据错误，并且允许复制数据。数据迁移方法不适用于存档存储时间短的磁盘，而是适用于存档存储时间长的磁盘。

ISO/IEC 29121:2009 provides specifications of the data migration method for archival data storage which allow manufacturers storage systems that use DVD-R (ISO/IEC 23912:2005), DVD-RW (ISO/IEC 17342:2004), DVD-RAM (ISO/IEC 17592:2004), +R (ISO/IEC 17344:2006 and ISO/IEC 25434:2007), and +RW (ISO/IEC 17341:2006 and ISO/IEC 26925:2006) disks for information storage to classify disk longevity potential on the basis of initial performance requirements and to allow users to monitor continuing conformance with the error limits required for its class identified by the manufacturer of the drive/disk. Digital data can be migrated to a next new disk without loss from the present disk as far as the data errors are completely corrected before and during the migration and the copy of the data is allowed.The methodology for data migration does not apply to disks with short archival storage time but to disks with long archival storage time.
