The phrase broken record refers to a malfunction when the needle skips/jumps back to the previous groove and plays the same section over and over again indefinitely. Phonograph records are generally described by their diameter in inches (12-inch, 10-inch, 7-inch) (although they were designed in millimeters ), the rotational speed in revolutions per minute (rpm) at which they are played ( 8 + 1⁄ 3, 16 + 2⁄ 3, 33 + 1⁄ 3, 45, 78), and their time capacity, determined by their diameter and speed (LP, 12-inch disc, 33 + 1⁄ 3 rpm SP, 10-inch disc, 78 rpm, or 7-inch disc, 45 rpm EP, 12-inch disc or 7-inch disc, 33 + 1⁄ 3 or 45 rpm) their reproductive quality, or level of fidelity (high-fidelity, orthophonic, full-range, etc.) and the number of audio channels ( mono, stereo, quad, etc.).

Since the 1990s, records continue to be manufactured and sold on a smaller scale, and during the 1990s and early 2000s were commonly used by disc jockeys (DJs), especially in dance music genres. By the 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the record left the mainstream in 1991. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. The phonograph record was the primary medium used for music reproduction throughout the 20th century. Starting in the 1940s polyvinyl chloride became common, hence the name 'vinyl'. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. The groove usually starts near the periphery and ends near the center of the disc.
