The vibration of the Gramophone's recording stylus was horizontal, parallel to the recording surface, resulting in a zig-zag groove of constant depth. This is known as lateral recording. Berliner's original patent showed a lateral recording etched around the surface of a cylinder, but in practice, he opted for the disc format.
The LP (from long playing [2] or long play) is an analog sound storage medium, specifically a phonograph record format characterized by: a speed of 33 + 1 ⁄ 3 rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the "microgroove" groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk.

Phonofilm is an optical sound-on-film system developed by inventors Lee de Forest and Theodore Case in the early 1920s. In 1919 and 1920, de Forest, inventor of the audion tube, filed his first patents on a sound-on-film process, DeForest Phonofilm, which recorded sound directly onto film as parallel lines. These parallel lines photographically ...
Unlike later, shorter-playing high-speed cylinders, early cylinder recordings were usually cut at a speed of about 120 rpm and can play for as long as three minutes. [5] They were made of a relatively soft wax formulation and would wear out after they were played a few dozen times. [10] The buyer could then use a mechanism which left their ...
