analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove

AI overview

A phonograph record is a flat disc with a spiral groove carved into it that stores sound in analog form, which can be played back when a needle tracks through the groove. These records were the primary way people listened to music and other audio for much of the 20th century before being largely replaced by digital formats.

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 a disc-shaped analog sound storage medium with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player").
