Charles Kroh scientifically established the principles of recording sound on a drum, and Thomas Edison invented and patented the «phonograph»
1939 year
During World War II, the supply of shellac decreased, so some disks were pressed from vinyl materials
BUGS SAVED THE MUSIC INDUSTRY
Shellac is a resin produced by tropical insects from South Asia. It had a light shade, but in combination with other components it gave an unpleasant dirty color. Then, in order to make the plate aesthetically pleasing, bone charcoal or petroleum soot was introduced into the composition of the mass and the disk became elegantly black
Edison Berliner developed the recorder to record sound and the «gramophone» to play back sound
Édouard-Léon Scott de Martinville was inspired by music boxes and created the «phonoautograph» on this principle
It was cheaper to make than ebonite, the predecessor of shellac. But the plates were heavy and as brittle as glass
Emil Berliner spent 10 years searching for the ideal material for shellac plastiks
THE FIRST BIRTH OF RECORDING
For 100 years, inventors have worked to create the optimal technology for sound recording and reproduction
