<p>In the security media ID of a security MO disc, a unique ID of a backed-up disc is written in 64 bytes following the unique ID of the security media ID of the for-backup disc. When using a security MO disc, the security media ID can be seen before performing password authentication. Accordingly, by comparing the unique ID of the backed-up disc in the security media ID of the for-backup disc to a unique ID of another disc, it is possible to rapidly find the backed-up disc of the for-backup disc.</p> |
