Handling of
magnetic recording tapes

In general no special attention is required in caring for the tape as a magnetic storage medium. However, his does by no means imply that the tape cannot be damaged by improper handling. By observing the following simple precautions the tape will live up fully to its reputation of being a reliable recording medium:
Use only brand name tapes of the high output/low noise variety. Our especially selected REVOX tape is recommended. The Revox A77 tape recorder is adjusted to yield optimum results with this tape.

Do not leave tape on the recorder when not in use as it will only collect dust. Store it away in its library box. Tape carton or library boxes should be stored in an upright position. If tapes are to be stored for extended periods of time try to insure fairly constant temperature and humidity conditions. Ideal values are 70° F (Fahrenheit (20° Celsius) and 40 to 60% of humidity. Elevated temperatures over long periods will adversely affect the layer to layer print through. A recommendation on tape storage which is contained in the NAB standard for magnetic tape recording reads as follows: It is good engineering practise when storing recorded tapes for long periods of time that the start of the programme be at the inside next to the hub. Tapes stored that way will have slightly less preprint than postprint. This is desirable because postprint tends to be masked by the programme material and reverberation effects. Also, rewinding a tape immediately before playing tends to reduce the print trough. A further advantage is that tape wound in the Play mode of operation usually is wound more smoothly than when wound at high speed. Magnetic recording tapes must be protected from strong magnetic fields. Partial erasure may result for example when placing a dynamic microphone on a reel of tapes or when bringing the tape too close to a switched on electric transformer.


Remark:
The operating instructions of the Revox A700, Revox B77 and Revox PR99 recommending exactly the same.
