TEST
TAPE
Test
tape
life
The
more
frequently
the
test
tape
is
used,
the
more
the
tape
characteristics
will
deteriorate
(e.g.
lowering
of
recorded
tevel,
worsening
of
frequency
response
particularly
in
high-frequency
range,
and
an
increase
in
wow
due
to
tape
elongation)
until
meas-
ured
values
become
unreliable.
Even
in
such
a
case
when
a
tape
is
not
used,
but
stored,
for
a
long
period
of
time,
tape
shows
deterioration
in
performance
because
of
self
damagenetization
due
to
storage
conditions,
etc.
Please
refer
to
the
tape
life
specification
and
use
care
not
to
use
a
