The History of Vinyl and CD .
In 1877 Thomas Edison was experimenting with a new telegraph devise when he accidentally runs indented tin foil under a stylus. The resulting speech like noise encourages him to develop an instrument that can both record and reproduce sound. By the end of the year Edison had produced the first working phonograph able to 'store' and playback sound.
Before Edison, others including Charles Cros had the idea, but were unable to fund them.
1885 Chichester Bell and Charles Tainter call the machine the "Graphophone" and utilise a wax coated cylinder incised with vertical-cut grooves.
1887 Edison updates the phonograph by using a solid wax cylinder and a battery-driven motor as opposed the original hand crank,giving a constant pitch.
1888 Emile Berliner invents the gramophone which used a 7 inch disc which was manually turned at around 30 rpm and had about a 2 minute record capability. The discs are made by acid engraving onto a zinc master, The advantage that the disc had over the cylinder is that it is possible to mass-produce a hard rubber record from the original press.
A material called shellac became available around 1910, and discs were produced in a range of sizes from 7 inch to 21in. .
Shellac was getting too brittle to transport around the world during the war, and around this time in the 40's Polyvinyl Chloride, PVC or vinyl for short ( which had been discovered 20 years before) became available.
New York CBS called a press conference to announce the introduction of the LP or long player. 12 inches wide, turning at 33 1/3 or 45 rpm the vinyl disc seemed a lot cheaper and easier to mass produce.It was a record that could contain up to 260 grooves or, more importantly, up to 30 minutes of music per side! .
By 1960 the golden age of vinyl had arrived, and theLP and single formats, supported by affordable turntables, amplifiers and loudspeakers were working well in the marketplace.
