Robotic System and Barcode Scanner
The robotic system identifies and moves the cartridges between the storage slots, tape drives, and the I/E
station. The robotic arm (picker) has picker fingers that enable it to grab tape cartridges and move them into
positions along X, Y, and Z motion coordinates. The robotic system and the barcode scanner work together
to identify the locations of resources within the library.
Each tape cartridge must contain a barcode that the barcode scanner reads during the inventory process.
During the inventory process, the barcode scanner reads the fiducial labels to identify the types of
magazines and tape drives that are installed in the library.
Every tape cartridge must have a unique machine-readable barcode attached to it. Tape cartridges cannot
have duplicate barcode labels. This barcode identifies the cartridge. The library stores the physical location
of the tape cartridge in an inventory database. All library or host requests typically reference the location of
the tape cartridges based on this barcode number. Barcode labels are mandatory and must adhere to
specific standards. For more information on barcodes, see
