Transcriptions of vibrations in air are perceptible as sound when stored onto such an apparatus such as a phonographic disc. However, in sound reproduction the process has to be reversed to enable the variations stored on the phonographic disc to be transformed back into sound waves. This is in relations to Michael Faraday's Law. There are three principal media, which has been developed for sound recording and reproduction, and they are the mechanical phonographic discs along with the magnetic systems such as the cassette tape and the optical system. The magnetic and the optical systems enable motion picture with in-built sound tracks and the latest concept being the digital compact disc. In the first six episodes of this feature "History of Vinyl ." I paid tribute to four great inventors and scientists of the past who in my opinion made it all possible in leading up to the advent of the vinyl records. Michael Faraday, Thomas Alvin Edison, Emil Berliner and Lee De Forest. The English chemist and physicist Michael Faraday known for his pioneering experiments in electricity and magnetism. Many scientists acclaimed him to be the greatest experimentalist who ever lived. |
