Guidelines For Bar Code Labels; Write-Protect Switch; Sample Bar Code Label On The Lto 8 Tape; Cartridge - Dell EMC ML3 User Manual

Attention: Do not place any type of mark on the white space at either end of the bar code. A mark in
this area might prevent the library from reading the label.
Figure 88. Sample bar code label on the LTO 8 Tape Cartridge. The volume serial number (LTO123) and bar code are
printed on the label.
Important: The bar code label must be applied as shown, with the alphanumeric characters on top and
the bar codes on the hub side (bottom). Never apply multiple labels onto a cartridge because extra labels
can cause the cartridge to jam in a tape drive.

Guidelines for bar code labels

Apply the following guidelines whenever bar code labels are used.
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 it is removed. If glue residue is 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 it is applied 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 takes 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 86 on page 143).
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 drive to load the cartridge.

Write-Protect switch

All rewriteable data cartridges have a write-protect switch to prevent accidental erasure or overwriting of
data. Before a cartridge is loaded into the device, make sure the write-protect switch on the front of the
cartridge is in the desired position.
The position of the write-protect switch on the tape cartridge (see 1 ) determines whether you can write
to the tape. If the switch is set to:
v Slide the switch to the right to write-protect the cartridge. An indicator, such as a red mark or small
padlock, is visible showing that the cartridge is write-protected.
