- 1840s Player pianos*
- 1877 Phonograph using a cylinder (Thomas Edison)
A video of the oldest recording made in 1860 by a Frenchman and recently recovered using modern technology--this recording was made by 'burning' sound waves onto paper! :
- 1894 Gramophone records
- 1898 Wire recording
- 1919 Sound on film
- 1925 Cut records
- 1940s Reel-to-reel tape recording
- 1947 Dictabelts
- 1948 LP (Long Playing) record on vinyl
An album (record) would have songs on both sides, and played at 33 1/3 rpm. They cost about $5.00. However, keep in mind a teen's allowance might be $5 a month. While thinner than shellac and not easy to break, vinyl records warp easily from heat: if you kept them in the sun or close to a heat source, they will curve out of shape, which ruins the sound.
- 1949 45 rpm record
This is what a record looks like when it's being played: The needle on the arm of the player is 'traveling' along the grooves of the record towards the hole in the middle. Hence, probably, the term "groovy."
In the 80s, DJs would usually have two players going at once and then move the turntable by hand to achieve the 'scratchy' sound popular at that time:
All recordings made by etching are actually one continuous spiral, whether on a cylinder or a vinyl record.
