deteriorate
(e.g.
lowering
of

level,
worsening
of
frequency
response
particularly
in
high-frequency
range,
and
an
increase
in
wow
due
to
tape
elongation)
until
measured
values
become
unreliable.
Even
in
such
a
case
where
a
tape
is
not
used,
but
stored,
for
a
Jong
period
of
time,
the
tape
shows
deterioration
in
performance
because
of
self
demagnet-
ization
due
to
storage
conditions,
etc.
