Hi, Lou,

We are starting to see some cassettes that benefit from baking.

Cassettes used thinner base film and mag coating plus very few (if any) 
were back-coated. This all contributes to less material to degrade to 
start with.

We have had several reports here of digital tapes needing to be baked, 
and they have thinner mag coats.

Cheers,

Richard

We are wondering why audio cassettes are so rarely having sticky-shed problems. I know that has been discussed occasionally here, but why are cassetes relatively immune?
