Recent Developments in the Field of Magnetic Recording
New magnetic recording media have been developed during recent years which will widen substantially the field of application for magnetic recording equipment. Probably most outstanding among the new recording media is the non-ferrous wire or tape, plated with a thin layer of nickel-cobalt alloy, and the paper disks and tapes coated with a dispersion of magnetic powder. — It might be of particular interest to the motion picture industry that the coated recording media can be perforated to obtain synchronization between picture and sound. It is also possible to apply the magnetic coating directly to the film base.
