Analog recording

Analog (or analogue) recording (Greek, ana is "according to" and logos "relationship") is a technique used to store signals of audio or video information for later playback.

Analog recording methods store audio signals as a continual wave in or on the media. The wave might be stored as a physical texture on a phonograph record, or a fluctuation in the field strength of a magnetic recording. This is different from digital recording, which converts audio signals into discrete numbers.

The first successful demonstration of analog recording for audio was by Thomas Alva Edison. The first analogs of moving pictures were those of the Lumiere Brothers.
