Phonograph cylinder

The earliest method of recording and reproducing sound was on phonograph cylinders. Commonly known simply as "records" in their era of greatest popularity (c. 1888 - 1915), these cylinder shaped objects had an audio recording engraved on the outside surface which could be reproduced when the cylinder was played on a mechanical phonograph. The competing disc-shaped gramophone record system triumphed in the market place to become the domininent commercial audio medium in the 1910s, and commercial mass production of phonograph cylinders ended in 1929.

Further improvements of commercial cylinders

Over the years the type of wax used in cylinders was improved and hardened so that cylinders could be played over 100 times. In 1902 Edison Records launched a line of improved hard wax cylinders marketed as "Edison Gold Moulded Records".

Hard plastic replaces wax

In 1906 the Indestructible Record Company began mass marketing cylinder records made of celluloid, an early hard plastic, that would not break if dropped and could be played thousands of times without wearing out. This hard inflexible material could not be shaved and recorded over like wax cylinders, but had the advantage of being a nearly permanent record. (Such "Indestructible" style cylinders are arguably the most durable form of sound recording produced in the entire era of analogue audio before the introduction of digital audio; they can withstand a great number more playbacks before wearing out than such later media as the vinyl record or audio tape.) This superior technology was purchased by the Columbia Phonograph Company. The Edison company then developed their own type of long lasting cylinder, consisting of a type of plastic called Amberol around a plaster core, these were called Amberol cylinders. Around the same time Edison introduced 4 minute cylinders, having twice the playing time of the old standard cylinder, achieved simply by shrinking the groove size and spacing them twice as close together in the spiral around the cylinder. Most (but not all) Amberol cylinders are of the four-minute variety. Edison phonographs for playing these improved cylinder records were called Amberolas. See also: Blue Amberol Records.
