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.
