Edison Diamond Disc Phonographs
1912-1929
With the competition from Columbia and Victor among others, Edison decided to introduce a Disc phonograph.   The disc format provided an easier possibility for record storage, not necessarily a better tone quality.  The earlier machines used amberola cabinets, but later machines were designed more for the distinct disc format.   The last disc machines were actually designed to play long-play records, up to 20 minutes on a side. <>
