Guidelines for Using Bar Code Labels

Apply the following guidelines whenever using bar code labels:

vDo not reuse a label or reapply a used label over an existing label.

vBefore you apply a new label, remove the old label by slowly pulling it at a right angle to the cartridge case.

vUse 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.

vExamine 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).

vRemove 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	in Figure 6-1 on page
6-1).

vWith light finger pressure, smooth the label so that no wrinkles or bubbles exist on its surface.

vVerify 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.

vDo not place other machine-readable labels on other surfaces of the cartridge. They may interfere with the ability of the drive to load the cartridge.

Write-Protect Switch

The position of the write-protect switch on the tape cartridge (see		) determines
whether you can write to the tape. If the switch is set to:
v The locked position	(solid red), data cannot be written to the tape.

vThe unlocked position (black void), data can be written to the tape.

If possible, use your server’s application software to write-protect your cartridges (rather than manually setting the write-protect switch). This allows the server’s software to identify a cartridge that no longer contains current data and is eligible
