The Edison Diamond Disc Record

The Edison Diamond Disc Record was a type of phonograph record first introduced by the Thomas Edison company in 1912 and produced until 1929. It was made of a hard, durable material called Condensite which consisted of a thin coating of a phenolic resin virtually identical to Bakelite on a core of compressed wood flour. The records were close to 1/4″ thick, much thicker than the popular 78 rpm shellac record.

The Edison Diamond Disc Record had several advantages over other cylinder style phonograph records of the time. The main advantage was that it played at a slower speed of 80 rpm, which allowed for longer playing time and better sound quality. Additionally, the groove on the record was wider and deeper, which allowed for a more precise reproduction of sound.

Another unique feature of the Edison Diamond Disc Record was its use of vertical recording, rather than the lateral recording used by other phonograph records. This meant that the stylus moved up and down rather than side to side, which resulted in a distinct and unique sound quality.

The Edison Diamond Disc Record was expensive, both to produce and to purchase. The phonographs that could play them were also expensive and not as widely available as other types of phonographs. Additionally, the use of vertical recording made it incompatible with other types of phonographs.

Despite these drawbacks, the Edison Diamond Disc Record was popular among audiophiles and collectors of the time. It was particularly prized for its superior sound quality, and many recordings of classical music and opera were made exclusively on Edison Diamond Disc Records.

The popularity of the Edison Diamond Disc Record began to decline in the 1920s, as newer technologies like electrical recording and the 78 rpm shellac record emerged. The last Edison Diamond Disc Record was produced in 1929, and the company discontinued the format shortly thereafter. Today, Edison Diamond Disc Records are sought after by collectors and remain an important part of the history of recorded sound.
