Thank you very much for your detailed instructions! I've tried using
plastibands from a Baumgarten assortment once but it didn't work for me. I
think the ones I used were the wrong size. They were very narrow once stretched
into place, and they wouldn't stay on the tape reels without slipping off and
terribly tangling everything up.
Coincidentally, I just got a food dehydrator for baking magnetic media before
archiving, to prevent oxide shedding. I'll be using it for 8" floppy diskettes
first. Does it matter whether baking is done before or after unsticking the old
band from the tape?

Is cyclomethicone lubricant helpful for imaging old edge-driven cartridges like
TU58, QIC, etc., or does it interfere with the belt drive?

I've ordered a bag of those Mobilon bands. I just typed in my name for the
company name when I registered, and their site seemed happy with that.
