The audio tape guys pretty much took the lead on this one, probably because they ran into the problem earlier. The reason for baking is to ameliorate the problem of binder degradation. It seems that baking at a mild temperature (there is a patent on this method), tends to "melt" the binder back into workability. If you've ever stuck a floppy into a drive and heard a loud squealing sound and wound up with a cookie with "see through" rings on it, you've experienced binder failure. There's quite a bit of information on this on the web. --Chuck
