Write-Protecting Cartridges
All cartridges have a write-protect (write-inhibit) switch to prevent
accidental erasure or overwriting of data. Before loading a cartridge into
the library, make sure that the write-protect switch is positioned correctly
(either on or off).
Slide the red or orange write-protect switch to the right so that the
padlock shows in the closed position. The switch is located on the left
side of the cartridge front.
Barcode Requirements
Cartridges must have an external barcode label that is machine and
operator-readable. A barcode must use only uppercase letters A to Z
and/or numeric values 0 to 9. The library supports Code 39 (3 of 9) type
barcodes.
The supported tape cartridge barcode formats are as follows:
• Standard Six — Six character barcode number with or without a one
or two-character media ID, for example, “XXXXXXL4” or ”XXXXXX”.
Only the six character barcode is reported to the host.
• Plus Six — Six character barcode number followed by a media ID, for
example, “XXXXXXL3”. Six character barcode and media ID are
reported to the host.
• Extended — Five to 16 characters total, including a barcode number
and optional media ID. All characters are reported to the host,
regardless of having a media ID or not. If a media ID is included, the
label must have a five to 14 character barcode followed by a media
ID, for example, “XXXXXXXXXXXXXXL2”. If a media ID is not
included, the label must have a five to 16 character barcode, for
example, “XXXXXXXXXXXXXXXX”.
• Media ID Last — Five to 14 character barcode number followed by
media ID, for example, “XXXXXXXXXXXXXXLT”. The media ID is
reported to the host last.
