Abstract
A recording head capable of applying an electric current, including an array of recording electrodes in the form of strips which are substantially equally spaced apart from each other in a direction perpendicular to lengths of the strips, by a distance smaller than the thickness of said strips. The strips include at least parts of generally elongate electrode portions of electrically conductive sheets superposed on each other in a predetermined relative position into an electrode assembly. The elongate electrode portions of each electrically conductive sheet is defined by a plurality of apertures whose width is larger than the thickness of each electrically conductive sheet. The elongate electrode portions of electrically conductive sheets cooperate with each other to define a plurality of slits whose width is smaller than the thickness of the sheet. The electrode portions of the electrode assembly functioning as the strips are spaced apart from each other by the width of the slits.
