Analog recording (Greek, ana is "according to" and logos "relationship") is a technique used for the recording of analog signals which, among many possibilities, allows analog audio and analog video for later playback. Analog recording methods store signals as a continuous signal in or on the media. The signal may 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 digital signals are represented as discrete numbers.
