Abstract
A matrix type magnetic recording/reading head made in integrated fashion, including an electrically non-conductive ceramic substrate having a first main face and a second main face, each provided with connection areas. The two areas of the two faces are interconnected in sets of two by internal connection elements. A layer with high magnetic permeability is deposited on the first face of the substrate. The substrate bears a first series of row conductors and a second series of column conductors intersecting the row conductors, each conductor being connected to a connection area of the first face. Pairs of magnetic poles are located substantially at the intersection of the row conductor and column conductors, the poles of each pair separated by a gap space and being magnetically coupled to the layer with high magnetic permeability in two opposite zones defined by the intersection of a row conductor and a column conductor.
