Vinyl record player history dates back to November 21, 1877 when Thomas Alva Edison announced his invention of the first phonograph, a device for recording and replaying sound. He demonstrated the device for the first time on November 29 (it was patented on February 19, 1878 as US Patent 200,521).
Edison's early phonographs recorded onto a tinfoil sheet phonograph cylinder using an up-down (vertical) motion of the stylus. The tinfoil sheet was wrapped around a grooved cylinder, and the sound was recorded as indentations into the foil.
Edison's early patents show that he also considered the idea that sound could be recorded as a spiral onto a disc, but Edison concentrated his efforts on cylinders, since the groove on the outside of a rotating cylinder provides a constant velocity to the stylus in the groove, which Edison considered more "scientifically correct".
Edison's patent specified that the audio recording was embossed, and it was not until 1886 that vertically modulated engraved recordings using wax coated cylinders were patented by Chichester Bell and Charles Sumner Tainter. They named their version the Graphophone...............
