The comments about the volume of reels being done having an effect on baking
times is something I have not observed.  What sort of apparatus are you
using?  We use laboratory grade incubators stable to within half a degree
with grated shelving to allow air flow, interior racks to hold tapes
separated by at least a few inches each and an air evacuation mechanism to
void the moisture extracted from the tapes.  We have not detected any effect
on needed baking times whether we have one 1/4" reel or twenty in an
incubation unit.  In fact, we have one unit where we can process 50 3/4"
tapes at a time without seeing any loss of effectiveness in the process.

Agreed, and you might try putting two hub spacers between each reel for
better air circulation.

Best,

John,
From my own observations in baking audio tapes, I've found that the more
tapes you bake at one time, the less effective the baking process is. It
takes exponentially longer with more reels. 12 seems like a huge amount to
be doing at once. Try your regular process, but cut the number of tapes in
half and see if it works any better.

Of course, I defer to the real experts here, so YMMV.
