Component Description
Tape Handling
A
tape
reel
that
is
not
in
use on a tape unit should always
be
stored
in
its container.
Establish
procedures
to
protect magnetic tape from contamination which causes
degraded tape unit performance. Some common rules are:
1.
Nllller leave tape reels or containers exposed. Tape may
be
damaged,
or
dust
accumulating on
the
tape
or
in
the container can contaminate
the
tape.
2. Erasing a tape reel identification label
is
a cause of contamination.
Use
new
labels when changing reel identification. Select a label with an adhesive
backing
that
does
not
leave a residue and
that
can be applied and removed
easily.
3. Never allow a loose end of tape
to
trail on
the
floor; dirt picked up
in
this
manner can reach the tape transport and be passed on
to
other
sections of
the
tape.
4. Do
not
allow smoking
in
areas where tape
is
in
use. Ashes contaminate tape.
Live ashes can permanently damage the tape surface.
5.
Don't
touch
the
tape edges through the
reel
openings or press on the reel
flanges. Such pressure will compress
the
tape and damage its edges.
6.
Be
very careful when removing the write-enable ring. Always unload tape
before removing
the
write-enable ring; never remove the ring while tape
is
loaded on the tape unit.
Tape

To
prevent tape contamination and damage during storage, follow these procedures:
1.
Before a tape
is
stored, secure the loose end of tape with a tape end retainer
to
prevent the taPe from unwindina
in
the container.
2. Use gum-free
type
labels only. -
3.
Always store tape
in
an upright position. Never store tapes flat or
in
stacks;
accidental damage
or
reel warpage may result.
4. Store tapes in a cabinet or shelf elevated from
the
floor and away from
sources
of
paper and dust. Dust can
be
transferred from the outside of the
container
to
the
reel
during load and unload operations.
5.
To
increase life of tapes and system performance, maintain library room
temperature
at
70°
to
75°F and humidity at 30%. Humidity
