Accessor

The accessor is composed of several components: robotic assembly, spooling mechanism, and bar code reader.

• The robotic assembly has fingers that enable it to grab tape cartridges and move them to and from the I/O station, storage slots, and drives.
• The spooling mechanism has a cable that extracts and retracts based on movement of the robotic assembly. This cable provides communication between the robotic assembly and the library main board.
• The high-speed bar code reader is a part of the Base Module. The bar code reader provides inventory feedback to the host application, Operator Panel display, and Management GUI by reading cartridge bar code labels. The library stores the customized inventory data in memory. Library firmware supports a 6 or 8 character volume serial number (VOLSER) on the bar code label on the tape cartridge. It is highly recommended to use bar code labeled cartridges. See Bar code label.
