Previous Page: Emil Berliner: inventor of the gramophone was the first inventor to introduce the flat disc similar to the vinyl records we are acquainted with today. He also put into practice electroforming to make negatives of the master disc, which could be served as master moulds to make further copies of the same tunes as what's on the original recordings; this principle is no doubt still evidently in use today. The early sound recording and reproduction was solely reliable on acoustical means. The 1920's saw the vacuum-tube amplifier, invented by American Lee De Forest Ph.D. The Vacuum Tube amps came into use, marking the transitional modification of the acoustical that brought about a change to electrical recording. Microphones took over from acoustical horns, and lo and behold the development of the modern electric phonographic amplified player. The electric phonograph amplified player consisted of a motor-driven turntable that incorporated a record-changing device, a cartridge, and loudspeakers. In June 1948, Columbia Records demonstrated their new 33 1/3-rpm long-playing format to its rival, RCA Victor hoping to ensure the success of the new format by convincing RCA to join with Columbia Records, but that was not to be, that demonstration infuriated the RCA Boss man. |
