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. To
obtain tape cartridges and bar code labels, see “Ordering media supplies” on page 54.
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 8. Cartridge data capacity and recording formats
Type Native Data Capacity Recording Format
Ultrium 8 12000 GB (30000 GB at 2.5:1
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,
16 tracks at a time.
Ultrium 5 1500 GB (3000 GB at 2:1 compression) Reads and writes data on 1280 tracks,
16 tracks at a time.
Ultrium 4 800 GB (1600 GB at 2:1 compression) Reads and writes data on 896 tracks, 16
tracks at a time.
Ultrium 3 400 GB (800 GB at 2:1 compression) Reads and writes data on 704 tracks, 16
tracks at a time.
Ultrium 2 200 GB (400 GB at 2:1 compression) Reads and writes data on 512 tracks, 8
tracks at a time.
Ultrium 1 100 GB (200 GB at 2:1 compression) Reads and writes data on 384 tracks, 8
tracks at a time.
The first set of tracks is written from near the beginning of the tape almost 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 (
▌2▐
Figure 11 on page 37) protects the tape from contamination when the cartridge is
out of the drive. The tape is attached to a leader pin (
▌3▐
in Figure 11 on page 37) 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 onto a non-removable take-up reel. The head can then read or write
data from or to the tape.
The write-protect switch (
▌4▐
in Figure 11 on page 37) prevents data from being written to the tape
cartridge. For more information, see “Write-Protect switch” on page 43.
