RE: arsclist Cassette Sticky-Shed
All
To
clarify a point raised by David Hoffman: I non-destructively separate a cassette
shell to expose the tape pack to allow for better air circulation around the
tape in the oven. When baking quarter inch tapes on reels, the reels go in
just as they are. Even if the reels are NAB reels made of two flanges and
a hub screwed together, these are left intact. Whenever we come across
sticky tapes we bake (all things being equal) before anything else. To run
a tape from one reel to the next even without head contact would run a very real
risk of stripping oxide from adhering layers. Even playing a sticky tape
at normal speed runs the risk of oxide stripping from adhering layers so I would
advise caution with David's NAGRA idea. David: when you use this extra
spindle idea do you achieve enough tape contact on the replay
head?

Dear all,
I have an alternative method to baking which has
been working for me. I also have a question re Nigel's suggestion for
removing one side of the reel when baking.
What I did was set up a
spindle near my Nagra on the play IN side of the tape recorder (as opposed to
the play out side). The spindle has absolutely no stress on it and as the
tape plays through the playhead, the spindle slowly turns. This eliminates
the squeak which is coming from pressure on the tape as it moves through the
play heads. I have completely eliminated squeaking this way.
Re Nigel's
suggestion. Nigel? Why don't you just run the tapes at high speed
through to a reel the where the top can be removed and then remove the top of
ever tape before baking?
Best regards,
