For long-term storage, the tape storage container should be sealed in a plastic bag. Store tapes in a cabinet or shelf elevated from the floor and away from sources of paper and card dust. This minimizes the transfer of dust from the outside the room. When vacuum equipment is used for cleaning, the exhaust outlet of the equipment should be located outside the room. Temperature and humidity control.
Tapes fare better in an environment that is clean and stable.
Magnetic tape ideally should be stored at a constant temperature of about 70 degrees Fahrenheit. If tape is stored at temperatures significantly above or below this figure, the tape should be stabilized in a temperature of 70 degrees Fahrenheit for 24 to 48 hours before it is used again. The air pressure in use in storage areas should be greater so that air flows out rather than in, helping keep contaminates from entering the storage area. Physical damage can occur. Tapes can be physically damaged in several ways.
