Tape Recording: Taking the Electromagnet to a Whole New Level

  • Rather than use electromagnets to cut a groove, why not use them with other magnets? By using materials that could be magnetized, the electromagnets used in the phonograph cartridge could be adapted into a magnetic recorder. This technology is still very much in use today, but in this episode of Technology Connections, we're exploring the two earliest forms of audio reproduction done with magnets: the wire recorder, and the magnetic tape recorder.
