本文档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，如果在迁移之前和迁移期间数据错误被完全纠正，并且允许数据的复制，则数字数据可以从当前磁盘无损失地迁移到下一个新磁盘。本文件规定:-用于长期数据存储的数据迁移方法；-测量最大数据误差的测试方法，包括环境条件、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错误表检查记录在磁盘上的数据的错误率；-减少变质可能性的预防措施，以确保盘在使用、储存、处理或运输过程中的完整性；和-Bmig(B0,000 1)寿命的估计寿命，以确定周期性性能测试的测试间隔。
This document 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 if data errors are completely corrected before and during the migration and provided copying of the data is allowed.
This document specifies:
- a data migration method for long-term data storage;
- test methods for measuring maximum data error, including ambient condition, test area, test drive, disk preparation and test execution;
- an initial performance test and a periodic performance test that check an error rate of data recorded on the disks with categorized maximum data error tables;
- precautions to reduce the possibility of deterioration in order to assure the integrity of the disks during their use, storage, handling or transportation; and
- the estimated lifetime of Bmig (B0,000 1) life to determine the test interval for the periodic performance test.
