Re: arsclist playback of deceliths

["George Brock-Nannestad" <pattac@xxxxxxxx>]

Hello, David and Bernd in particular, but otherwise all interested in 
mechanical recordings:

Decelith came in two types: before ca. 1938 there was only the 
transparent type, solid stock, and they were covered with a waxy 
lubricant. Ca. 1938 a new type appeared: black and rubbery layers 
on a white (yet to be determined, but probably cellulose acetate) 
carrier layer. These latter were considerably more flexible, and they 
were actually manufactured post-war in Germany. I have obtained a 
small stock of unrecorded discs of both types and am currently 
planning some experiments in cutting signals onto them (I regularly 
use a 78rpm record cutting machine). And obviously I will also 
reproduce them afterwards to determine the "transparency" of the 
system. A report will be forthcoming.

Kind regards,


George
