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 tape is processed 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:
Table 15. Cartridge Data Capacity and Recording Formats

compression) Reads and writes data on 6656 tracks,
32 tracks at a time.
Ultrium 7 6000 GB (15000 GB at 2.5:1 compression) Reads and writes data on 3584 tracks,
32 tracks at a time.
Ultrium 6 2500 GB (6250 GB at 2.5:1 compression) Reads and writes data on 2176 tracks,

The first set of tracks is written from close to the beginning of the tape to close to 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 (

in Figure 107 on page 91) protects the tape from contamination when the
cartridge is out of the drive. The tape is attached to a leader pin (
