ABSTRACT:
A high resolution magnetic printing head possesses a comb-like magnetically permeable member formed by electrodeposition. A magnetic printing head comprising a substrate with an elongated gap across which conductive lines pass is formed by electrodeposition of magnetically permeable material between adjacent wires on a substrate. A special jig facilitates electrodeposition with a constant flow of electrolyte through the gap and between the wires during the plating process. A single such substrate with its associated gap and conductive wires is employed in certain applications, however, a dual or triple substrate configuration with each substrate and its associated set of wires being aligned with each other substrate and set of wires is preferred for use in a coincident current printing head.
