Data Cartridge
The different generations of Quantum Ultrium data cartridges can be
identified by color:
All generations contain 1/2-inch, dual-coat, magnetic tape.
You can order tape cartridges with the bar code labels included, or you
can order custom labels.
When processing tape in the cartridges, Ultrium Tape Drives use a linear,
serpentine recording format. The native data capacity and recording
format of Ultrium data cartridges is as follows:
The first set of tracks is written from near the beginning of the tape to
near the end of the tape. The head then repositions to the next set of
tracks for the return pass. This process continues until all tracks are
written and the cartridge is full, or until all data is written.
The cartridge door (2 in Figure 8
on page 66) protects the tape from
contamination when the cartridge is out of the drive. The tape is
attached to a leader pin (3 in Figure 8
on page 66) behind the door.
When the cartridge is inserted into the drive, a threading mechanism
pulls the pin (and tape) out of the cartridge, across the drive head, and
