Analog (or analogue) recording (Greek, ana is "according to" and logos "relationship") is a technique used for the recording of analog signals which among many possibilities include audio frequency, analog audio and analog video information for later playback.
Analog recording methods store 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 of which among many possibilities include digital audio and digital video, which digital signals are represented as data or discrete numbers.
The first successful demonstration of analog recording for audio was by Thomas Alva Edison.[1] The first analogs of moving pictures were those of the Lumiere Brothers.[2]
