Abstract
A high resolution magnetic printing head comprises a pair of interlaced printed circuit board structures. Each printed circuit board structure comprises a two or three layer assembly in which each layer comprises a flexible printed circuit board having an elongated gap therein with electrically conductive signal lines crossing the gap. On each three layered structure, the signal lines on adjacent circuit boards are substantially parallel where the lines cross the gaps in the printed circuit boards. The two printed circuit board structures are adjacently disposed so that their respective elongated gaps are aligned but so that the conductive signal lines are interlaced. High permeability magnetic material is then deposited between said interleaved signal lines by electrodeposition so as to form magnetic pole pieces between the conductors bridging the elongated gaps.
