Data cartridges
Use the LTO data and cleaning tape cartridges designed for your model of library.
When tape is processed in the cartridges, LTO Tape Drives use a linear, serpentine recording format. The
native data capacity and recording format of LTO data cartridges is as follows:
Table 45. Cartridge data capacity and recording formats
Type Native Data Capacity Recording Format
Gen 8 12000 GB (30000 GB at 2.5:1
compression)
Reads and writes data on 6656 tracks,
32 tracks at a time
Gen 7 6000 GB (15000 GB at 2.5:1 compression) Reads and writes data on 3584 tracks,
32 tracks at a time
Gen 6 2500 GB (6250 GB at 2.5:1 compression) Reads and writes data on 2176 tracks,
16 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.
The cartridge door (▌2▐ in Figure 86) protects the tape from contamination when the cartridge is out of
the drive. The tape is attached to a leader pin (▌3▐ in Figure 86) behind the door. When the cartridge is
