I have some old tapes that the magnetic side is seperating from the
clear tape...any way to freeze or heat so that it binds back
togetherr to copy them.....? thanks

NO.... it is done, over, kaput, etc.

There are apparently 2 options as you mention: baking and freezing.

The baking is done using "metal" reels in a preheated oven between
110' to 120'F for 4 to 6 hrs (use a precise themometer, not the
oven's). Many range ovens start at 150'F so these are unsuitable.

Freezing takes longer and is done for a period of 2 to 3 months.

The idea behind both methods is to drive out the moisture.

Perhaps vacuum freeze drying is another possibility and perhaps faster
than both the above.

One other technique concerns a special tape lubricant cloth that used
to be popular but I have no idea if it is to be found anywhere or what
it was made of.

A*s*i*m*o*v

Thank you for the information....

If the oxide coating is already peeling away from the plastic medium
then getting rid of moisture isn't going to help. And the difference
in the coefficients of expansion in the materials will only make the
problem much worse if you expose the tape to significant temperature
changes.

Trying to play the tape will ruin the heads of your playback device.

I would strongly believe that your tapes are "F***ed"! I would doubt that
there is any way to fix them.

I was simply retelling a method officially approved by Ampex.
You might try and contact them to warn them.
