<P> A phonograph record ( also known as a gramophone record , especially in British English , or record ) is an analog sound storage medium in the form of a flat disc with an inscribed , modulated spiral groove . The groove usually starts near the periphery and ends near the center of the disc . At first , the discs were commonly made from shellac ; starting in the 1950s polyvinyl chloride became common . In recent decades , records have sometimes been called vinyl records , or simply vinyl . </P>
