Analog recording

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.

Audio

The modern examples of analog audio recording are:
*Gramophone record (also known as a "phonograph record", "vinyl", etc).
*Magnetic tape, magnetic tape sound recording
*Wire recording

Video

The earliest forms of video recording used analog technology. John Logie Baird developed a system in the 1920s for the storage of video signals on conventional phonograph records, which he called Phonovision. In the 1930s, he further developed the Intermediate Film Technique, which provided for an analog method of temporary video storage by using cine film.
