While this produced a very quiet recording, moisture often caused this bonded layer to separate or develop raised “lamination cracks” rendering the recording useless. After mid-1916, this layer of resin varnish was applied directly onto the core. While it eliminated the peeling and cracking, it resulted in considerably higher surface noise that took Edison another four or five years to bring under control., The Edison Diamond Disc is unlike nearly every other record ever made.
