They spin the disc, which sounds as though it was recorded in a ditch.

At first few record players could spin a disc at 45rpm, but no matter - there was a communal player just right for the new format: the jukebox.

The deck spins the disc at 33/3 revolutions per minute for standard albums or 45rpm for singles and so-called audiophile albums.

All involve spinning the disc to give it gyroscopic stability, and accelerating its mass to a certain velocity.

When power was applied and the front cover closed, a spindle engaged the center hole of the disc and a motor-driven idler wheel spun the disc on the spindle.
