2.5 Reliability

Tandberg Data and its employees and suppliers are committed to providing quality
products. The SDLT tape drive system is a very reliable electromechanical device.
2.5.1 Positive Engagement Tape Leader Buckling
Mechanism
This buckling mechanism is responsible for engaging the tape leaders upon
cartridge load and disengaging them upon cartridge unload. The SDLT tape
buckling mechanism has been designed to work with the new leaders of the SDLT
tape drive design as well as the leaders of the previous DLT drive design, allowing
backward-read compatibility of DLTtape IV cartridges in the SDLT tape system.
Component level tests of buckle arm components have shown at least 250,000
cycles on an SDLT drive without failure, breakage, or binding; this includes the
take-up leader, the supply leader, and the media itself.

2.5.2 MTBF

Mean time between failures (MTBF) for the overall tape system is projected to be
250,000 hours. Head life is a minimum of 30,000 tape motion hours and an
average of 50,000 tape motion hours. Media durability is 1,000,000 passes.
