Access to the archive compartments and the drives is facilitated with the handling unit. The handling unit executes the commands of the AML Management Software (AMS) and returns status messages as response.

The handling unit is equipped with a (laser) barcode scanner. Typical tasks of the handling unit are inserting and ejecting cartridges, placing and gripping cartridges in the archive, mounting the connected drives with the cartridges and reading a barcode label attached to the car- tridges.
