My bet is, this won't work. The boxes probably have varying degrees of moisture, plus there may be
elements of the boxes like glue or ink from markings/writing on them that may not be stable at
tape-baking temperatures. Plus, the whole point of baking a tape in a convection or air oven is to
circulate the heat in and around the tape-pack. At least that's my understanding.
I've never had a mega-batch of tapes to bake, but I did have 20 reels once. The air oven only
handles 4 or 5 at a time. I set up a folding table to do this, so I could keep everything in perfect
order. I was lucky in that most of the reels were clearly labelled in a way that I could match them
with their boxes. But I still stacked the empty boxes in the order that the reels were placed in the
air oven. At first I was going to bake them all and then transfer them, but the table was set up out
of the way in the house (under the stairs), so I baked them 4 or 5 at a time, transferred those,
then did the next batch. It worked well. If I had been putting in full-time days, I could have baked
the next batch during the day while I was transferring a batch, then let the newly-baked tapes cool
overnight and start the process again until finished. I was operating part-time in the studio, so it
wasn't quite that efficient, took me a few weeks to get thru all the tapes. They were 1-mil 3600'
tapes recorded at 3.75IPS, mostly air-checks. Not my favorite job, content-wise, but the results
were better than expected. That was Ampex 407 tape and it required the full monty of 12 hours baking
and 12 hours cooling, but it did play perfectly after baking.
