Easily assembled transverse magnetic printing head

A transverse magnetic printing head driven in a coincident current mode in which there are (W.times.D) recording gaps organized into W adjacent word segments, each word segment having D independent digits, said head comprising:

• a rigid supporting member having a transverse slot therein;
• a comb structure of high magnetic permeability material with teeth forming (W.times.D) recording gaps between the tips of said teeth, said comb structure being received into the transverse slot of said supporting member in such a manner that the teeth of said comb structure protrude above said supporting member;
• an insulated word line drive circuit with W independent word lines, each of said word lines forming a zig-zag pattern spaced so as to match the spacing of the teeth on the comb structure, each of said word lines repeatedly crossing said transverse slot and threading through a selected one of said recording gaps, said word line drive circuit being mounted in a flush manner against said supporting member so as to align the magnetic comb structure with said transverse slot;
• and
• an insulated digit line drive circuit with D independent digit lines, each digit line, d.sub.i, for i ranging from 1 to D, being spaced and laid out in such a manner so as to thread through the i.sup.th recording gap position in alternate word segments and through the (D-i+1).sup.th recording gap position in the remaining word segments, each such digit line also repeatedly crossing said transverse slot, said digit line drive circuit being mounted in a flush manner either over or under said word line drive circuit so as to align the magnetic comb structure with the transverse unsupported gap region.
