I was reading about the Phonograph the other day
A phonograph record is a flat disc with inscribed spiral grooves
Yeah they said that it was revolutionarynat the time 
They were first made from shellac but in the 1950's , they made them out of vinyl
I have a lot of old records like those?
My mother has some too. The phonographic disc record was the primary thing used for music until the 20th century.
That is not that long ago really
By the late 1980's the compact disk took over and records left the mainstream in 1991.
