What is Media ID mean when backups written to Disk means

When I look for backup id's in GUI catalog, Backups written to disk have media ID's @aaaax or @aaaav etc.,

Whats this media ID, and when is it assigned?

Does each disk pool or Disk stu have unique media id? Is this media ID static?

It is the ID of the disk pool. Each pool created will have on such as that.

For all other disk based storage units and storage pools, a relative ID is assigned for each storage unit upon creation.

This Media ID is formatted with an asperant ("@") followed by a "one-up" lettering system. The first disk storage unit (including Basic Disk) created is assigned "@aaaaa", the second "@aaaab", and so forth. Once all the lower case letters have been assigned, the pattern repeats with the upper case letters, so after one pass through the next assignment would be "@aaaaA".
