Tape cartridges are intended for nominal program or
data storage; the typical life cycle is 50-100 hours,
dependinj! on the
app~cation.
Environmental conditions of
25°C
(77
F) and 20 to 50% relative humidity are most
favorable for a long tape life. Tape life is decreased by a
high duty cycle (percent of of time the tape is accessed
during the total time the 9825 is in use), high turning
resistance and continuous use for long periods of time
(longer than one-half hour) It is suggested that tape
transports be regularly cleaned and cartridges removed from
drives after use.
For heavy usage of mass storage files, such
as
in
consecutive file sorts or data base management applications,
flexible disc drives are recommended for optimum
performance and reliability.
