Guidelines for using LTO bar code labels
The guidelines listed in this topic must be followed when using LTO bar code
labels.
Apply the following guidelines whenever you use LTO bar code labels:
v
Use only IBM-approved bar code labels.
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 they are 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 you apply it to the cartridge. Do not use the label if it
has voids or smears in the printed characters or bar code (an application'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 bar code label area.
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.
v
Do not place other machine-readable labels on other surfaces of the cartridge.
They might interfere with the ability of the bar code reader to read the bar code.
Setting the write-protect switch on an LTO tape cartridge
Use the write-protect switch to prevent data from being written to an LTO tape
cartridge.
The position of the write-protect switch on an LTO tape cartridge (see
▌1▐
in
Figure 31 on page 122) determines whether you can write to the tape:
v
If the switch is set to (solid red), data cannot be written to the tape.
v
If the switch is set to unlocked (black void), data can be written to the tape.
