Bar Code Labels
A bar code label contains:
v A volume serial number (VOLSER) that is human-readable
v
A bar code that the library can read
Note: The tape drive does not require bar code labels, but you may choose to use
labels for tape cartridge identification purposes.

When read by a library's bar code reader, the bar code identifies the cartridge's
VOLSER to the library. The bar code also tells the library whether the cartridge is a
data cartridge, WORM cartridge or cleaning cartridge. In addition, the bar code
includes the two-character media-type identifier
Lx , where x equals 1, 2, 3 or T.
“Bar Code Labels” shows a sample bar code label for the LTO Ultrium Tape
Cartridge.

*An Ultrium 3 Tape Drive must have a minimum firmware level of 54xx for it to be compatible with the WORM
cartridge.
Tape cartridges can be ordered with the labels included or with custom labels. To
order tape cartridges and bar code labels, see “Media Supplies” on page C-4. The
