ABSTRACT:
A method for fabricating high resolution magnetic printing head wherein a comb-like magnetically permeable member is formed by electrodeposition. The 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 conductive lines positioned on the substrate. A special jig facilitates electrodeposition by ensuring constant flow of electrolyte through the gap and between the conductive lines during the plating process. A single substrate with its associated gap and conductive lines is employed in certain applications. However, a dual or triple substrate configuration, wherein each substrate and respective conductive lines are aligned with each other, is preferred in a coincident current printing head.
