How is analog signals stored?

Analog signals are typically stored using methods that capture their continuous waveform. Common storage mediums include magnetic tapes, vinyl records, and analog audio cassettes, where the variations in the signal are physically represented by grooves or magnetic patterns. In more modern contexts, analog signals can also be digitized and stored in digital formats, but the original analog representation involves directly encoding the continuous variations of the signal. This allows for the playback of the original signal with its full range of nuances.
