Computer diskettes Diskettes have many of the same physical characteristics of other electromagnetic media and are vulnerable to the same hazards. Don't store near magnetic fields or in a high temperature environment. Discard the plastic sleeves in which they come. Theses leeves can create static and erase your disk. Relative humidity is the single most important factor in preserving photographs from chemical deterioration.
Damage caused by fungi and other microorganisms is irreversible.
Temperature control is improtant mostly because of its influence on relative humidity. However, high temperatures will speed up chemical deterioration. Fahrenheit is the recommended compromise temperature for the storage of photographs and the comfort of people, but lower temperatures are desirable, expecially for color materials. Stable conditions are very important. Photographic materials are hygroscopic, readily absorbing and releasing moisture.
