Phonographic cylinder
The phonographic cylinder is the ancestor of the disc. When, in August 1877, Thomas Edison invents the Phonographe, it records the sounds on a cylinder covered with a sheet of tin. The April 30th 1877, Charles Cros had deposited a report which recommended this method. The cylinder of Wax, black or brown, one two minutes duration, will be sophisticated in 1908. The Edison company will leave the blue cylinder of Bakélite, one four minutes duration.
The cylinder had at the beginning a great disadvantage, it did not exist any solution to duplicate it. The Artiste S were thus obliged to record to them Prestation as much of time than the number of desired cylinders of same the recording. But the production became industrial in the brothers Pathé with the use of several systems, initially thanks to a system derived from the Pantographe, a system to read a cylinder and to engrave some another at the same time, then with the discs moulded to arrive at a production of 3000 cylinders per day in 1905. The phonographic Disc, invention of Emile Berliner in 1889 had many advantages, and will replace the cylinder.
