A disk, in the context of a record, refers to a flat, circular object used to store audio or data. Traditionally, vinyl records are made of polyvinyl chloride and are played on a turntable using a needle that reads the grooves on the disk's surface. This technology allows for the reproduction of sound, making it a popular medium for music. In addition to vinyl, disks can also refer to compact discs (CDs) and digital versatile discs (DVDs), which store digital data. These disks are read by lasers in CD players or DVD players, allowing users to access music, movies, or other information stored on them.
