1.3.4 Reliability (Projected)

Mean time between failures (MTBF) for the tape system is projected to be 250,000 hours
at 100% duty cycle, not including heads; 300,000 hours at 20% duty cycle, not including
heads. Life of recording heads is 30,000 hours, minimum; 50,000 hours, average.
Media durability is projected to be 1,000,000 passes of the tape medium across the
read/write heads (15,000 uses). One tape pass is defined as any point on the tape
passing the head in either direction.
Quantum Corporation does not warrant that predicted MTBF is representative of any
particular unit installed for customer use. Actual figures vary from unit to unit.
