ABSTRACT:
In order to achieve higher resolution in printed data, separate magnetic printing head sub-assemblies are adjacently disposed with respect to each other. Each sub-assembly includes a high permeability magnetic comb structure with teeth protruding through elongated slots in a pair of flexible printed circuit boards. High resolution is achieved by a relative offset of the comb teeth so that the teeth of the comb in the second sub-assembly align with the gaps in between the comb teeth in the first sub-assembly.
