recording on cylinders
The Phonograph was great at the time but it was only good for a one time only playback and the sound quality was terrible. 10 years after the Phonograph was invented Emile Berliner came up with the Gramophone. He was the first inventor to stop recording on cylinders and start recording on flat discs or records. The first records were made of glass. Later on they were made of zinc and eventually plastic -
a motor for the gramophone
Johnson made a motor for the gramophone to keep it at a steady speed instead of hand-cranking the records. -

The records had a spiral groove etched into it with sound information that the "arm" of the gramophone, which held a needle, would run through while being hand-cranked and play the sound through the gramophone speaker.
