Abstract
In order to increase the resolution and visual quality of the image produced by the transverse magnetic imaging technique, a magnetic printing head has an odd number of stacked elongated comb-type recording head sub-assemblies which are offset relative to each other in the elongated direction. Individual word and bit coincident current-type conductors are wound the gaps between the teeth of each comb such that unidirectional current will generate in the adjacent gaps of each comb magnetic fields in opposite directions along the length of each comb and such that the magnetic fields in like-ordered gaps of adjacent combs are also in opposite directions. The resultant magnetic image in a magnetic medium moving adjacent the printing head in a direction perpendicular to the lengths of the combs is thus composed of interleaved recordings of alternating directions, which, as compared with single and double comb structures, are spaced much closer together and may be continuously inked with toner on another medium, such as paper, to produce a bolder, higher contrast, and more readable image with a higher image resolution.
