Injected Noise Specifications
The internal drive operates without degradation of error rates with 100 
mV of noise injected between the chassis and 0 V at the power 
connector at any frequency between 45 Hz and 20 MHz.

Mean Time Between 
Failures
• The mean time between failures (MTBF) for the internal drive is 
specified at 250,000 hours minimum. This specification includes all 
power-on and operational time but excludes maintenance periods. 
Operational time is assumed to be 100% of the power-on time. 
Operational time is the time the tape is loaded.
The MTBF for the tabletop drive power supply is 50,000 hours with the 
unit operated at full load and 25°C. 
Note:The MTBF rating does not represent any particular drive, but is 
derived from a large database of test samples. Actual rates may 
vary from unit to unit. 
Mean Time to ReplaceThe mean time to replace (MTTR) is the average time required by a 
qualified service technician to diagnose a defective drive and to install a 
replacement drive. The MTTR for LTO products is less than 0.5 hour (30 
minutes).
The LTO drives are field-replaceable units. If a problem occurs with a 
subassembly or component in the drive, you should replace the entire 
unit. Return the drive to the factory in its original packaging. Contact 
your distributor, dealer, your computer system company or your sales 
representative to arrange the return. Mean time between 
failures (MTBF)250,000 hours MTBF at 100% duty cycle: 
power applied and tape moving

Environmental 
Considerations
Ta b l e  1 0 lists the basic environmental tolerances for LTO Ultrium 
cartridges. 
Table 10  Environmental 
Tolerances
If during storage and/or transportation a cartridge has been exposed to 
conditions outside the specified values, it must be conditioned before 
use in the operating environment. The conditioning shall be exposure to 
the operating environment for a time equal to, or greater than, the time 
away from the operating environment, up to a maximum of 24 hours. 
There shall be no deposit of moisture anywhere on or in the cartridge.
The stray magnetic field at any point on the tape shall not exceed 4000 
A/m.
Cartridge MemoryEach Ultrium 1, 2, and 3 cartridge has 4 Kbytes of nonvolatile memory:
• 3 Kbytes are used to store tape-directory and hardware specific 
information. 
• 1 Kbyte is available for application and OEM use. 
Each Ultrium 4 and 5 cartridge has 8 Kbytes of nonvolatile memory:
• 4 Kbytes are used to store tape-directory and hardware-specific 
information.  Specification Value
Maximum localized temperature-
permanent tape damageGreater than 52°C
Operating temperature 10°C to 40°C
Relative humidity 10% to 80% storage,

• 128 bytes are used for error information. 
• Approximately 4K bytes are not used.
The cartridge memory is powered, read, and written to via a radio-
frequency link.
Cartridge ReliabilityAfter 5,000 load/eject cycles, replace the cartridge to insure data 
integrity.
