This part of IEC 62702-1 specifies a method of data-quality assurance for writable disks (hereinafter “disks”) which are specified for long-term data storage, and a data migration method, which can sustain the recorded data on disks for long-term audio data preservation. The writable disks include BD Recordable disk and BD Rewritable disk.<\/p>\n
