Name:   Grooves in a 78 rpm phonograph record
Copyright:   Copyright 2009 Dennis Kunkel Microscopy, Inc.
Description:   Caption: Surface recording grooves of a 78 rpm phonograph record. Early disc phonograph records (also called gramaphone records) were made of various materials including hard rubber. From 1897 onwards, earlier materials were largely replaced by a rather brittle formula of 25% shellac, a filler of a cotton compound (similar to manila paper), powdered slate, and a small amount of a wax lubricant. Vinyl (polyvinyl chloride) was used as a 78 rpm record material starting in 1940. These records had much less noise and less ability to break. A phonograph record is an analog sound storage medium consisting of a flat disc with an inscribed modulated spiral groove usually starting near the periphery and ending near the centre of the disc.
