<p>An easily assemblable transverse magnetic printing head and method for making same are disclosed for use in a coincident current, matrix-driven, transverse printing head. In accordance with one embodiment of the present invention, digit lines pass through a recording gap in mirror image fashion as between adjacent word groupings. Similarly, the word line patterns are arranged on a printed circuit board in a zig-zag fashion. A feature common to both the word and digit line printed circuits, however, is the presence of a small expanse of circuit wiring unsupported by printed circuit substrate material through which a high permeability magnetic comb structure is inserted to form required recording gaps. The coincident current scheme is retained by driving the digit lines from alternating directions. The arrangement of the digit lines in the present invention permits the use of a planar printed circuit with no crossovers and therefore a circuit which is easily fabricated in a flexible, printed circuit design.</p> |
