Vinyl Record (12-inch LP)
Analog audio stored in microscopic grooves/Musical Instruments
A 12-inch vinyl LP record stores about 22 minutes of audio per side in a continuous spiral groove that, if unwound, would stretch about 460 meters. The groove is about 40-80 micrometers wide, and the needle (stylus) vibrates in response to variations as small as 1 micrometer. LPs have outsold CDs every year since 2020, and revenue from vinyl now exceeds $1 billion annually in the US.
