Records before vinyl were made of what. A phonograph record also known as a gramophone record especially in british english or simply a record is an analog sound storage medium in the form of a flat disc with an inscribed modulated spiral groove. Any flat disc record made between about 1898 and the late 1950s and playing at a speed around 78 revolutions per minute is called a 78 by collectors. An interesting economic situation has arisen due to the geographical location of the lac producing bug and its special tree largely within what was the british empire before indian independence. The materials of which discs were made and with which they were coated were also various.
Shellac eventually became the commonest material. Also these new records were made of a vinyl compound rather than the easily breakable shellac of 78s. During and after world war ii when shellac supplies were extremely limited some 78 rpm records were pressed in vinyl instead of shellac wax particularly the six minute 12 30 cm 78 rpm records produced by v disc for distribution to us troops in world war ii. At first the discs were commonly made from shellac with earlier records having a fine abrasive.

New vinyl made up a vastly smaller share of the market in the mid 90s than it did before the cd whether we re talking about albums or singles. The groove usually starts near the periphery and ends near the center of the disc. New lp discs were made of pvc vinyl and played with a smaller tipped microgroove stylus at 33 1 3 rpm.

Introduced in 1948 lp long playing albums were a huge improvement on the existing shellac 78 rpm records that were both brittle and limited to less than five minutes of playback time per 12 inch side. However vinyl s lower playback noise level than shellac was not forgotten.
