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.
