Cartridge storage systems
The archive system deposits a cartridge at any storage location which it knows. For recognition purposes, the cartridges bear machine-readable barcode labels.
Input/output unit
The archive systems provide robot-operated input/output units so that cartridges can be passed to or removed from the closed archive system.
The design and usage of the input/output unit differ for the archive systems:
The Scalar i500 archive system has one input/output unit which is used by all partitions of the archive system.
In the Scalar i6000 archive system each input/output unit is assigned to a particular partition of the archive system.
These differences must be taken into account when cartridges are imported and exported, see the notes in section "Importing and exporting cartridges".
