I thought the members of this list might find this interesting:
Recently, some 1/2-inch Sony DASH (3324) format tapes were shipped from
the UK to the Warner Bros. Sound Transfer Dept in Burbank, CA. The tapes
would not play and exhibited Sticky-Shed Syndrome.
I was asked if I thought it would be safe to bake the tapes. My response
was that it could be risky and if we were to attempt it, the tapes should
be baked at a much lower temperature for 24 hours or so. It was decided to
try my suggestion since there was nothing to loose at this point.
3 reels of Quantegy 1/2-inch 467 Digital audio tape, originally recorded
in August of 1999.
2 reels of Quantegy 1/2-inch 467 Digital audio tape, originally recorded
in May of 2004.
The tapes were baked for 16 hours at 118 degrees F. and then left in the
oven for 6 additional hours as the oven cooled. The decision was made to
end the baking at 16 hours because the Transfer Dept. Supervisor wanted to
test the results to see if there was any improvement that might warrant
further baking. The first tape tested played just fine so each tape was
tried in succession with the same positive results.
