transcription disc

Many of the transcription discs in the Yiddish Radio Project collection looked like this when first found. The white film on the surface is not dust but a chemical exuded from the disc itself and is the most apparent sign of nitrocellulose acetate decomposition. The shiny patches at the top left of the disc are places where the recording surface has flaked off, revealing the aluminum base beneath.
