How magnetic tape is made

National Audio Company president Steve Stepp guides viewers through the production of magnetic tape. Note that this is just one way of making tape; in metal evaporate tape, the magnetic material (Iron Oxide (Type I), Chromium with Cobalt (Type II), Metal particles (Type IV, or in this case, metal layer since applying particles in a vacuum chamber is impossible) is applied in a vacuum chamber. This process is used for Type I, II, IV, (cassette tape) metal particulate (LTO tape)/particle (DV tape) and BaFe (LTO) tape. Type IV and metal particulate/particle are similar. from
