<p></p><p>Abstract We built a magnetic wire recording platform from the scrap of a classic Webster-Chicago recorder. The restored wire recorder uses a motor to control coupled gears and to move trolleys carrying a wire passing through an inductive head. The sound picked up by a microphone is recorded directly within the wire by the inductive head and the same head performs the reading by a reciprocal process. We compared the recorded signal directly from the recording head with the same signal with distortion correction (DC and AC bias) and discussed the signal to noise ratio and distortion of recordings on steel wires.</p><p></p>
