System performance is optimized by channel calibration.
System performance is further optimized by a feature that is called channel calibration, in which the drive automatically customizes each read/write data channel to
compensate for variations in such things as the recording channel 's transfer function, the media, and characteristics of the drive head.
Power management
The LTO tape drives feature a power management function. This function controls the drive's electronics so that part of the electronics completely turns OFF when circuit
functions are not needed for the drive's operation.
Supported tape cartridges
The library supports LTO tape cartridges.
Within the library, the supported LTO tape drive uses the following cartridge types:
Data cartridge
WORM (Write Once, Read Many) cartridge
Cleaning cartridge
All generations contain 1/2-inch, dual-coat, and magnetic tape.

1. 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.
2. When tape is processed in the cartridges, Ultrium tape drives use a linear, serpentine recording format.
3. Cartridge initialization time may vary. For more information, see Media optimization.
4. The library Firmware must be at 0080 or greater and drive firmware must be at HB82 or greater to support the LTO M8 media feature. To know more about Ultrium
M8 tape cartridges, see LTO type M cartridge (M8).
For more information, see LTO media.
Library functions
The library provides many specific functions, such as alerts and logging, random and sequential logical library modes, and encryption.
