Bar code label requirements for Ultrium tape drives and libraries Ultrium Tape Drive/Library Bar Code Label Requirements 3580 Not required 3581 Required 3582 Required 3583 Required 3584 Required When read by a library's bar code reader, the bar code identifies the cartridge's VOLSER to the library. The bar code also tells the library whether the cartridge is a data cartridge or cleaning cartridge. In addition, the bar code includes the two-character media-type identifier Lx, where x equals 1, 2, or 3. L identifies the cartridge as an LTO cartridge. 1 indicates that the cartridge is the first generation of its type; 2 indicates that the cartridge is the second generation of its type; 3 indicates that the cartridge is the third generation of its type. Figure 9 shows a sample bar code label for the LTO Ultrium Tape Cartridge. Tape cartridges can be ordered with the labels included or with custom labels. To determine the complete specifications of the bar code and the bar code label, contact your sales representative. When attaching a bar code label to a tape cartridge, place the label only in the recessed label area ( 4 ). A label that extends outside of the recessed area can cause loading problems in the drive. Attention: Do not place any type of mark on the white space at either end of the bar code. A mark in this area may prevent the library from reading the label. L T O 1 2 3 L3 a69i0082 Figure 9.
