And then there's always the mold that comes with moisture, which I've seen literally eat away old
Scotch 111 acetate tape. So here's the typical options for typical old tapes stored in typical
old
private collection -- keep those tapes in the cold/moist/likely moldy garage or basement or keep
those tapes in the hot attic. Basement -- they can get eaten away and/or warp. Attic -- they
warp
and might get so brittle that they won't play or get something akin to lost lubricant.
Yeah, folks, if you have something valuable to you or to posterity on reels, for heaven's sake
transfer the darn thing and till your digital garden regularly!
