Barcode Labels
This document describes the requirements for cartridge barcode labels used in Oracle’s
StorageTek tape libraries. All tape cartridges must have a proper barcode label.
Mis-aligned, mis-oriented, or improperly-labeled cartridges may cause equipment
damage.

Barcode Standards
StorageTek libraries use labels based on the Code 39 barcode standard (refer to
ANSI/AIM BC1/1995, Uniform Symbology Specification - Code 39). This standard
uses discrete barcodes, meaning a fixed pattern of bars represents a single character.
Each character is made up five black and four white, where three bars are wider than
the others.
For example, Figure H–1 represents the letter A using six narrow bars and three wide
bars (two black and one white).
Figure H–1 Code 39 Barcode Standard — Letter A
When multiple barcode characters are arranged together as a label, a narrow white bar
is placed between the individual characters. This bar is called the inter-character gap.
