Previous Page: By this time the cylindral Phonographs was having wide public acceptance success on the US market, a contrivance that had already gone through quite a lot of years developing. Emile Berliner's Gramophone, which used discs pressed in hard rubber instead of cylinders got underway with very little supportive backing in 1893. Emil Berliner was in hope of attracting more substantial backers by presenting the unique advantages of the Gramophone. These flat discs were much cheaper to fabricate and a numeral amount could be copied from a zinc master. Emil Berliner based his model on Scott's Phonautograph and Cros's disc machine design.
Emil Berliner's description of his Gramophone record augmentation is as follows: "A talking machine in which a sound is first traced into a fatty film covering a metal surface and which is then subjected to the action of an acid or engraving solution which consume the record into the metal. This record being an incessant wavy line of even deepness is then revolved, which not only pulsates and duplicates the sound chamber but also propels the equivalent by holding its stylus in the record groove." The original record can be reproduced infinitum (Time without end - continual reproduction from the master copy).
