In addition to its system control functions, the Expansion Unit has a
16-cartridge magazine with a random access robotic mechanism. The module
robotics moves cartridges between the PTM and any of the 16 cartridge
storage locations.
You can designate a magazine in one of the MiniLibrary Base Modules as a
mail slot for inserting or removing one or more single cartridges, which
implements the SCSI IMPORT/EXPORT commands.
NOTE:
A magazine that has been reserved for import/export service can not be used for
data storage.
MiniLibrary Base Module
The MiniLibrary Base Module (Figure 1-2) has one or two DLT tape drives
and a 10-cartridge magazine with a rugged random access robotic mechanism.
The drives use the DLT tape IV cartridges, which provide a native capacity of
20 GB, 35 GB, or 40 GB per cartridge depending on the drive type. All models
can also read and write DLTtape III and DLT tape IIIxt cartridges. Both read
and write densities are selectable from the front panel, and under SCSI control
from the host. These units are available as differential rack-mount or table-top
versions, as well as a single-ended table-top-only version.
