Barcode Media Label Requirements for Dell
PowerVault Tape Libraries
This document provides guidance to customers on LTO media label requirements to ensure
operation in Dell’s tape libraries.
The relevant Dell tape libraries are:
• PowerVault 124T
• PowerVault TL2000 \ TL4000
• PowerVault ML6000 family
If non- Dell barcode labels are required for business reasons, the following requirements must be
met to ensure the label is machine readable by the Dell tape libraries. Dell- supplied barcode labels
provide the best results as they have been fully qualified and meet the required standards.
Note: Checksum characters are not supported on barcode labels.
• Comply with 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 (10mil).
• 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.
Dell tape libraries support the following tape cartridge barcode formats:
• Standard — Five to 16 characters total, including a barcode number and optional two- character
media ID. If a media ID is included, the label must have a five to 14 character barcode number
followed by a media ID; example, “XXXXXXXXXXXXXXL4”.
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.
If a media ID is not included, the label must have a five to 16 character barcode number; example,
“XXXXX” or “XXXXXXXXXXXXXXXX”. Note that only the barcode number is reported to the host.
• Standard Six — Six character barcode number with or without a two character media ID;
example, “XXXXXXL4” or ”XXXXXX”. Note that only the six character barcode number is reported to
the host.
• Plus Six — Six character barcode number followed by a two- character media ID; example,
“XXXXXXL4”. The six character barcode and media ID are reported to the host.
