The effects of mold growth on both the integrity of the tape and the recorded sound or image can be significant. Mold growth often sticks the tape layers in a tightly packed reel together at one edge. If the affected tape is wound or played, this can rip the tape.
Mold develops on tapes that have been stored in less-than-optimum conditions. It is important to remember that moldy tape is a hazard, not just for the individual tape. If not handled carefully, it can potentially spread to other parts of your collection, so it must be treated immediately.
What can Creative Audio Works do to help?
Most tapes infested with mold are treatable and can be effectively played back following the appropriate procedures. Occasionally, mold growth is so extensive that it damages the binder irreparably. Mold can also aggravate other problems associated with compromised tape, such as binder hydrolysis, a form of degradation affecting magnetic tape, resulting from the deterioration of the binder and characterized by the deposit of a gummy residue on the tape heads during playback usually referred to as Sticky Tape Syndrome
ADAT tapes and digital recordings recorded on the Sony F1 format (VHS tape) can sometimes have a mold apperance due to improper storage. It is actually a binder issue similar to Sticky Shed Syndrome in an audiotape.
If you do find mold on your tapes, all is not lost. With careful, specialized treatment, the material can be recovered. Action does need to be taken promptly, however, in order to salvage the tape and prevent the spread of further infection.
