Re: [ARSCLIST] Tape baking question

David:

As long as you don't have acetate or some very early, heat sensitive 3M
formulations, there is seldom a problem with baking the entire tape.  Even
with the early 3M, as long as you bake the tape at a lower temperature for a
longer time, there should be no serious problems.  The major problem with
baking non-hydrolyzed, poly-base analog audio tapes is that it can weaken or
destroy the adhesion of the splices.  If you are planning, as an
alternative, to separate the sections, the weakening of splices is a minor
inconvenience.

I invented the cold-desiccation process and, while it is very helpful in
many circumstances, it is time consuming and not, always, the best
alternative.  If you simply have "sticky-shed" (binder hydrolysis), it may
not be necessary.  If you have inter-wrap adhesion or binder-base adhesion
problems, then it can be a necessity.

Best of luck with your project.  I hope this e-mail was at least somewhat
coherent- I just arrived in Alaska and the time (and cultural) difference
between here and "the real world" can be somewhat brain-numbing.

Subject: [ARSCLIST] Tape baking question

Here's one for the team. Let's say you have a reel made up of several short
pieces of tape, either a compilation or a master or just something where it
was
convenient to group similar pieces of material together. Let's say SOME of
the
selections are recorded on 176, some on 456, some on god knows what....and
of
course, now you have a tape that has sticky shed on only some of the tracks.
Do
you bake the whole thing or try and remove only the portions that need
treatment and bake them?
