[ARSCLIST] storage of mothers, masters, and stampers
Can anyone provide guidance on the proper storage of metal mothers,
masters, and stampers?
We are preparing a collection of such discs for long-term storage in
a collections storage facility (where it is 50º F +/-1º and 38% RH
+/- 3%). The items are 13-14 in. in diameter, and appear to be made
of nickel, copper, and possibly zinc (or alloys of same?). I can't
help but wonder if most of the likely standard-issue archival
housings -- the buffered sleeves and boxes designed for transcription
discs -- are not be perfectly suited in terms of design and materials
for these kinds of sound recordings.
Are custom enclosures required? Do the conventional shelving
guidelines -- vertical, not too tight, etc. -- apply? Any information
or ideas are welcome.
