Cartridge Compatibility

Data Cartridge

When processing tape in the cartridges, Ultrium Tape Drives use a linear,
serpentine recording format. The Ultrium 3 drive reads and writes data on 704
tracks, sixteen tracks at a time. 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.
Figure 9-1. The IBM TotalStorage LTO Ultrium 400 GB Data Cartridge
The cartridge door ( 2 in Figure 9-1) protects the tape from contamination when
the cartridge is out of the drive. Behind the door, the tape is attached to a leader
pin ( 3 in Figure 9-1). 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 9-1) prevents data from being written to the
tape cartridge. For more information, see "Write-Protect Switch" on page 9-7.
