Vinyl record

The vinyl record is an audio storage medium, most commonly used for preserving music. It is a subset of the family of analogue disc records (see).

A vinyl gramophone or phonograph record consists of a disc of polyvinyl chloride plastic, engraved on both sides with a single concentric spiral groove in which a sapphire or diamond needle or stylus is supposed to run, from the outside edge towards the centre.

Vinyl records are made in the following formats:

Common formats

• 12" 331/3 rpm long-playing (LP) format
• 7" 45 rpm (single) format

Less common formats

• 12" 45 rpm extended-playing (Maxi Single) format
• 10" 331/3 rpm long-playing (LP) format
• 10" 45 rpm extended-playing (EP) format
• 7" 331/3 rpm extended-playing (EP) format
• 16 rpm format for voice recording

Some late 78rpm records were also pressed in vinyl.

Although replaced by digital media such as the compact disc as a popular mass marketed music medium, vinyl records continue to be manufactured and sold in the 21st century. Currently the most common formats are:

• 12" / 45 rpm Maxi Single
• 12" / 33 rpm LP

followed by

• 10" / 45 rpm EP
• 7" / 45 rpm Single

The sound quality and durability of vinyl records in highly dependent on the quality of the vinyl used.
