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.
For the native data capacity and recording format for Ultrium data cartridges, see Table 2 on page 2.
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▐ in Figure 108 on page 97) protects the tape from contamination when the
cartridge is out of the drive. The tape is attached to a leader pin (▌3▐ in Figure 108 on page 97) 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 108 on page 97 prevents data from being written to the tape
cartridge. For more information, see “Write-Protect switch” on page 103.
The label area (▌5▐ in Figure 108 on page 97) provides a location to place a label. .
The insertion guide (▌6▐ in Figure 108 on page 97) is a large, notched area that prevents the cartridge
from being inserted incorrectly.
