A novel magnetic transducer for magnetographic printing

Magnetic transducers for magnetographic printing consists of a long array of individual heads, each serving to magnetize a small region on a drum, coated with a standard magnetic media recording surface. The head elements are energized in a fashion that is similar to the firing of the pins in a dot-matrix print head. In this way the drum surface is magnetized in a pattern that represents text or picture. Toner particles are attracted to, and adhere to the magnetized patterns, and nowhere else. Transferring this toner pattern to paper, and fusing the toner into the paper surface completes the printing process. This paper describes a novel transducer for performing the magnetic printing of dots onto a magentic drum.
