Appendix D: The Tape Cartridge

Always observe the proper environmental conditions for the storage of tape cartridges. Refer to the cartridge reference card supplied with each cartridge. The ambient operating environment for the tape cartridge is:

Temperature

10°C to 40°C (50°F to 104°F)

Relative Humidity

20% to 80% (non-condensing)

If storage and/or transportation of a tape cartridge have exposed it to conditions outside the ambient values above, you should “condition” the tape cartridge to its operating environment for a 24-hour period.

When placing tape cartridges in archival storage, make sure you stand each tape cartridge vertically.

Do not place cartridges on or near devices that may produce magnetic fields such as computer monitors, motors, or video equipment. Such exposure can alter or erase data on the tape. Note that magnetic fields are not generally a problem since their strength decreases as inverse of the distance from the source cubed. Unless very near (within a few inches) a magnet or an electric motor there is no problem. The earth exerts a magnetic field everywhere of less than about 0.5 Oersteds. The field from a tape that is read by a recording head is about 100 Oer. To disturb the information on the tape would require a field larger than this and to erase the recorded information a field larger than the coercivity of the tape is required which would be about 2000 Oer. field strength.

Never apply adhesive labels or POST-IT notes on the top, side, or bottom of your DLTtape cartridge. Only use the user slide- in type label provided with each cartridge and slide it over the label slot on the cartridge.

Do not carry cartridges loosely in a box or any other container. Allowing cartridges to hit together exposes them to unnecessary physical shock.

Do not touch or allow direct contact with tape or tape leader. Dust or natural skin oils can contaminate the tape and impact tape performance.
