Current Libraries - Barcodes - HP LTO Ultrium Technical Reference Manual

Current libraries — barcodes
Many libraries use sticky labels with barcodes on cartridges to identify them. These are read by a
barcode reader attached to the picker arm. The application then needs to hold information as to the
contents of the tape to which it can relate the bar code.
Cartridge Memory can be used as a substitute for these barcodes. No human interaction is needed
to fix barcode labels, reducing errors, though cartridges may still need labels that humans can read.
A cartridge can be identified by its serial number.
However, because Cartridge Memory has space that can be written by applications, it can hold
details of the contents and nature of the tape. This obviates the need for this information to be held
by the application. HP is working with other industry leaders, both hardware and software, on an
Industry Common Implementation Guide.
