ISO/IEC 18630:2023

This 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.
