Re: [ARSCLIST] Storing 16" transcription discs
>2. Is anyone familiar with foil-lined sleeves? I have not seen any
imprinting or other problems with the discs, but is there concern
of outgassing or any other problems?
These may be a type of sleeve known as the "shield pack". As far as I know
they have been discontinued not because the sleeves off-gassed but, because
they inhibited air exchange (i.e. created a micro-environment)and seemed to
in fact accelerate the degradation of lacquered discs, which of course do
I seem to recall that they were developed at least in part by the Library
of Congress and, if that's so, someone from LC could probably give you a
more complete history.
