Barcode Label Requirements
Cartridges must have an external barcode label that is machine readable.
Dell-supplied barcode labels provide the best results. Barcode labels from
other sources can be used, but they must meet the following
requirements:
• ANSI MH10.8M-1983 Standard.
• Font: Code 39 (3 of 9).
• Allowable characters: Uppercase letters A to Z and numeric values
0 to 9.
• Number of characters: 5 to 16 (default for LTO is 6+2).
• Background reflection: Greater than 25 percent.
• Print contrast: Greater than 75 percent.
• Ratio: Greater than 2.2.
• Module: Minimum .254 mm (10 mil).
• Print tolerance: ± 57 mm.
• Length of the rest zones: 5.25 mm ± 0.25 mm.
• No black marks may be present in the intermediate spaces or rest
zones.
• No white areas may be present on the bars.
Note:
Checksum characters are not supported on barcode labels.
Note:
A maximum of 12 characters is recommended. A barcode
label with more than 12 characters may not be printable
according to the Code 39 label specifications for the tape
cartridge area to which the label is attached. The effective
tape cartridge barcode label length, including any media
ID, may be limited to a maximum of 12 characters.
