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.

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 level is impor·
