Phonograph cylinders (also referred to as Edison cylinders after its creator Thomas Edison) are the earliest commercial medium for recording and reproducing sound.Commonly known simply as "records" in their heyday (c. 1896–1916), a name which has been passed on to their disc-shaped successor, these hollow cylindrical objects have an audio recording engraved on the outside surface which can ...
Test pressings were made at the normal 12-inch and 10-inch sizes in addition to the 7-inch sizes noted below for both 8 + 1 ⁄ 3 as well as 16 + 2 ⁄ 3.

Blue Amberol Records was the trademark name for cylinder records manufactured by Thomas A. Edison, Inc. in the US from 1912 to 1929. They replaced the 4-minute black wax Amberol cylinders introduced in 1908, which had replaced the 2-minute wax cylinders that had been the standard format since the late 1880s.

Blue Amberols are more commonly seen today than earlier Edison 2-minute ...

Three vinyl records of different formats, from left to right: a 12 inch LP, a 10 inch LP, a 7 inch single. A phonograph record (also known as a gramophone record, especially in British English) or a vinyl record (for later varieties only) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove.
Edison introduced wax cylinders approximately 4 + 1 ⁄ 4 inches (11 cm) long and 2 + 1 ⁄ 4 inches (5.7 cm) in external diameter, which became the industry standard. [1] They had a maximum playing time of about 3 minutes at 120 RPM , but around the turn of the century the standard speed was increased to (first 144) and then 160 RPM to improve ...
In the Pathé recording studios, masters were cut on what was called a "Master Cylinder", rapidly spinning wax cylinders that measured about 13 inches (33 cm) long and 4 + 1 ⁄ 2 inches (11 cm) in diameter. [4] Beginning in 1913, special "Paradis" cylinders about 8 inches (20 cm) in diameter and 8 + 1 ⁄ 2 inches (22 cm) long were used. The ...
