信息技术.信息交换和储存用数字记录介质.DVD-R、DVD-RW、DVD-RAM、+R和+RW光盘用数据迁移方法

[中文适用范围]： 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、CDRW、BD 可刻录光盘和 BD 可重写光盘的数据迁移方法。通过应用本文档进行信息存储，如果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，则可以将数字数据迁移到下一张新光盘，而不会造成现有光盘的丢失。 [外文原描述]： 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.
