A gramophone record, also known as a phonograph record or vinyl record, is a flat disc made of vinyl or other materials used for storing analog sound recordings. Other synonyms for a gramophone record include LP (long-playing) record, EP (extended play) record, single, 45 (referring to the revolutions per minute the record turns), and album. In the digital age, terms like CD (compact disc), MP3 or digital record have become popular, but gramophone records have enjoyed a resurgence in recent years among audiophiles and collectors, ensuring that these synonyms for the iconic record format remain in use.
