A recording in which continuous magnetic signals are written to the tape that are representations of the voltage signals coming from the recording microphone or the video camera.
Magnetic tape analog storage systems record on a tape a magnetization which is directly proportional to the signal. A sound recording on tape is also an analog recording. High volume intensity results in heavy magnetisation, low volume intensity results in weak magnetisation. Photographic film is also referred to as analog storage. The density is directly proportional to the brightness.
