query: What is wire recording or magnetic wire recording?
answer: Wire recording, or magnetic wire recording, was the first magnetic recording technology. It's an analog audio storage method where a magnetic recording is made on thin steel wire.  The wire is pulled across a recording head that magnetizes it according to the audio signal.  Playback involves drawing the wire across a head to induce an electric current, recreating the sound.
