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 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
5
in Figure 4-1 on page 4-1). 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.
Guidelines for Using Bar Code Labels
Apply the following guidelines whenever using bar code labels:
v Use only IBM-approved bar code labels on cartridges to be used in an IBM tape
library.
v
Do not reuse a label or reapply a used label over an existing label.
v Before you apply a new label, remove the old label by slowly pulling it at a
right angle to the cartridge case.
v Use peel-clean labels that do not leave a residue after being removed. If there is
glue residue on the cartridge, remove it by gently rubbing it with your finger.
Do not use a sharp object, water, or a chemical to clean the label area.
v
Examine the label before applying it to the cartridge. Do not use the label if it
has voids or smears in the printed characters or bar code (a library's inventory
operation will take much longer if the bar code label is not readable).
v Remove the label from the label sheet carefully. Do not stretch the label or cause
the edges to curl.
v
Position the label within the recessed label area (see
5
in Figure 4-1 on page
4-1).
v With light finger pressure, smooth the label so that no wrinkles or bubbles exist
on its surface.
v Verify that the label is smooth and parallel, and has no roll-up or roll-over. The
label must be flat to within 0.5 mm (0.02 in.) over the length of the label and
have no folds, missing pieces, or smudges.
