Inherent Vice & other Preservation Issues

Composition and Moisture

Due to their composition, Edison Diamond Discs tend to absorb moisture easily and with disasterous effects. If subjected to enough moisture, the record can warp, delaminate, and crack. Early Diamond Discs, which were made with celluloid, are especially vulnerable.

The following images, courtesy of The Edison Phonology Website, all illustrate common problems associated with discs exposed to moisture while in storage.

   

Chipping

Careless handling can result in chipped edges on an Edison Diamond Disc. Minor chipped edges that do not effect the grooves should not affect playback, but be careful of where you place the stylus.

   

Scratches

As with any other disc media, Edison Diamond Disc playback can be significantly altered by scratches on or across the grooves. Perpandicular scratches create an annoying, loud "CLICK" every time the record makes one revolution, while also putting stress on the stylus tip. Scratches on a more horizontal angle might cause the stylus to skip and keep repeating the same groove over and over again.
