That is acknowledged in the slides, isn't it?

"Thermal Baking: A popular, poorly understood remedy"

"Most common remediation (successfully used for decades)"

"No consistent baking procedures - to this day audio tape users argue 
about about why it works."

I am trying to read a bunch of late 80s QIC-24 tapes (Sun/Computervision 
install media). In addition to the normal QIC band problem, I am seeing 
problems with the tape sticking on the metal posts that the tape goes 
around to change direction towards the reels. Should I try wiping the 
posts with acetone or wiping the tape with cyclomethicone? Should I be 
baking the tapes? If so, what is a safe way to bake QIC cartridges?
