[ARSCLIST] Loss of Lubricant and A- and B-winds

["Richard L. Hess" <ArcLists@xxxxxxxxxxxxxxx>]

Ok, an interesting thought occurred to me through an off-list discussion.

In normal practice, as I understand it, the "Lubricant Package" was 
thrown into the coating vat and is coated on the tape along with the oxide.

So, for A-wind tapes, the lubricant theoretically lubricates 
everything - tape passing over guides and heads.

I'm starting to wonder where the stiction occurs in cassettes, since 
they are B-wind, the back of the tape passes over guides (most are 
rotating) but doesn't have any lubrication. I'm wondering if we can 
glean anything from the German Radio B-wind tapes though I know most 
of those are rotating guides as well.

I had assumed (I know that's dangerous) that most of the stiction in 
cassettes was from the heads themselves.

Any thoughts would be appreciated.

I hypothesize that LoL will become a growing problem - and baking 
exacerbates it.

Cheers,

Richard
