ISO/IEC 29121:2018规定了用于长期数据存储的DVD-R、DVD-RW、DVD-RAM、+R、+RW、CD-R、CD-RW、BD可记录和BD可重写磁盘的数据迁移方法。通过将该文档应用于信息存储，只要在迁移之前和期间数据错误被完全纠正，并且允许数据的复制，数字数据就可以从当前盘无损地迁移到下一个新盘。ISO/IEC 29121:2018规定:-用于长期数据存储的数据迁移方法；-测试方法，包括测试参数、测试区域、测试驱动、磁盘准备和测试执行；-初始性能测试和周期性性能测试，其用分类的最大数据误差表检查记录在磁盘上的数据的可读性；和-必须采取预防措施以减少变质的可能性，以确保盘在使用、储存、处理或运输过程中的完整性。ISO/IEC 29121:2018提供了使用估计寿命为Bmig（B0,000 1）寿命的磁盘的指南，该寿命是使用ISO/IEC 16963中规定的B5寿命和B50寿命引入的。

ISO/IEC 29121:2018 specifies the data migration method for DVD-R, DVD-RW, DVD-RAM, +R, +RW, CD-R, CD-RW, BD Recordable and BD Rewritable disks for long-term data storage. By applying this document for information storage, digital data can be migrated to a next new disk without loss from the present disk as long as data errors are completely corrected before and during the migration and provided copying of the data is allowed.
ISO/IEC 29121:2018 specifies:
- a data migration method for long-term data storage;
- test methods including test parameters, test area, test drive, disk preparation and test execution;
- an initial performance test and a periodic performance test that check a readability of the data recorded on the disks with categorized Maximum Data Error tables; and
- a necessity of precaution to reduce the possibility of deterioration in order to assure the integrity of the disks during their use, storage, handling or transportation.
ISO/IEC 29121:2018 offers guidelines to use disks with estimated lifetime of Bmig (B0,000 1) Life which is introduced using B5 Life and B50 Life specified in ISO/IEC 16963.
