Bar Code Label
The 3580 Ultrium 2 Tape Drive does not require cartridge bar code labels.
However, if you use your data cartridges or cleaning cartridges in an IBM tape
library product, you may need cartridge bar code labels if your tape library
product requires them. A label contains:
v
A volume serial number (VOLSER) that you can read
v
A bar code that the library can read
When read by the 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 or cleaning cartridge. In addition, the bar code includes the
two-character media-type identifier
Lx
, where
x
equals 1 or 2.
L
identifies the
cartridge as an LTO cartridge.
1
indicates that the cartridge is the first generation
of its type;
2
indicates that the cartridge is the second generation of its type.
Figure 8 on page 29 shows a sample bar code label for the LTO Ultrium Tape
Cartridge.
You can order tape cartridges with the labels included, or you can order custom
labels. To order tape cartridges and bar code labels, see “Ordering Media Supplies”
on page 43. The bar code for usage in IBM tape libraries must meet predefined
specifications. They include (but are not limited to):
v
Eight uppercase alphanumeric characters, where the last two characters must be
L1
or
L2
v
Label and printing to be non-glossy
v
Nominal narrow line or space width of 0.423 mm (0.017 in.)
v
Wide to narrow ratio of 2.75:1
v
Minimum bar length of 11.1 mm (0.44 in.)
To determine the complete specifications of the bar code and the bar code label,
visit the web at
http://www.ibm.com/storage/lto
(select either Technical Support
or LTO Support), or contact your IBM Sales Representative.
When attaching a bar code label to a tape cartridge, place the label only in the
recessed label area (see
4
in Figure 7 on page 25). A label that extends outside of
the recessed area can cause loading problems in the drive.
Attention:
Do not place any type of mark on the white space at either end of the
bar code. A mark in this area may prevent the library from reading the label.
