Re: [ARSCLIST] Storing 16" transcription discs

Hi, Marcos.

We are fortunate to have original square tin boxes for storing our
transcription discs. These hold several discs which we separate using
Tyvek. They feature a central bolt that passes through the discs and
supports them in the middle so no other part of the disc bears any
weight.  The lacquer over the edge of a transcription disc can be very
thin. The weight of a 16 inches disc on this may, over time, trigger
cracking or delamination.

All the best

Subject: [ARSCLIST] Storing 16" transcription discs

Dear all,

I am currently surveying a collection of 1950s 16" transcription discs.
They have been stored flat in foil-lined paper sleeves and are generally
in pretty good shape.

I have two questions for those with the knowledge:

1. Are there storage concerns specific for 16-inchers? Does their extra
mass affect the recommendation for vertical storage (for example,
shelving with dividers closer together)?

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? Would you recommend something a little
stiffer?

Thank you in advance to all of you.

Marcos
