Content DescriptionThis document specifies a quality discrimination method for optical disks and the operating method of storage systems for long-term digital data preservation using optical disks and optical disk drives (hereinafter referred to as "drives"). It is applicable to recordable (write-once) optical disks which can prevent physical overwriting and deletion by erroneous or intentional operation in contexts where greater importance is given to evidence. It is also applicable to read-only (ROM) optical disks. This document specifies: —    combinations of recordable optical disks and drives used for long-term data preservation; —    quality discrimination criteria for recordable optical disks and the operation method of long-term storage systems; —    a quality test for read-only optical disks and the operation method of long-term storage systems; —    quality discrimination criteria for BD recordable disks when adopting defect management. About ISOISO, the International Organization for Standardization, brings global experts together to agree on the best way of doing things – for anything from making a product to managing a process. As one of the oldest non-governmental international organizations, ISO has enabled trade and cooperation between people and companies all over the world since 1946. The International Standards published by ISO serve to make lives easier, safer and better. |
