Grafonola
The Graphophone was the name and trademark of an improved version of the phonograph. It was initially designed at the Volta Laboratory established by Alexander Graham Bell in Washington, D.C., United States. It was co-invented by Alexander Graham Bell, Charles Sumner Tainter, and Chichester Bell in 1886. Its trademark usage was acquired successively by the Volta Graphophone Company, the American Graphophone Company, the North American Phonograph Company, and finally by the Columbia Phonograh Company (known today as Columbia Records), all of which either produced or sold Graphophones. Research and development It took five years of research under the directorship of Benjamin Hulme, Harvey Christmas, Charles Sumner Tainter and Chichester Bell at the Volta Laboratory to develop and distinguish their machine from Thomas Edison's Phonograph. Among their innovations, the researchers experimented with lateral recording techniques as early as 1881. Contrary to the vertically-cut g ...

The Volta Laboratory was founded in 1880–1881 with Charles Sumner Tainter and Bell's cousin, Chichester Bell, for the research and development of telecommunication, phonograph and other technologies.

Phonograph Disc
A phonograph record (also known as a gramophone record, especially in British English) or a vinyl record (for later varieties only) 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 outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side. For about half a century, the discs were commonly made from shellac and these records typically ran at a rotational speed of 78 rpm, giving it the nickname "78s" ("seventy-eights"). After the 1940s, "vinyl" records made from polyvinyl chloride (PVC) became standard replacing the old 78s and remain so to this day; they have since been produced in various sizes and speeds, most commonly 7-inch discs played at ...
