There are two types of magazines: one for DLT and another for LTO.
Because the two magazines are the same size, they can be mixed in the
library. DLT magazines hold five cartridges, and LTO magazines hold six
cartridges.
Each magazine has a barcode label that the scanner reads for
identification and inventory. An optional, snap-on dust cover is available
for the magazines. Magazines with the dust cover have interlocked
stacking that enables easier storage of the media when they are removed
from the library for external storage.
Support for WORM
The Scalar i2000 library supports WORM (write once, read many)
technology in LTO-3 and LTO-4 tape drives. WORM requirements
