    CPC classification number: H04N3/14

    Abstract: An information display system is provided which comprises a body of material serving as both a substrate for thin film components and a medium for the propagation of Rayleigh acoustic waves along its surface. The thin film components include elements responsive to the Rayleigh waves to provide information at selected locations on the surface of the body. These components may be either the control elements or the output elements of the display system.

    Abstract: A MAGNETIC DIGITAL RECORDING HEAD OF COMB TYPE, CAPABLE OF PACKING DENSITIES, FOR EXAMPLE, ON THE ORDER OF ONE MILLION BITS PER SQUARE INCH OF RECORDING MEDIUM, IN WHICH A CORE STRUCTURE IS CONSTRUCTED TO EXTEND ACROSS A COOPERABLE MAGNETIZABLE RECORDING MEDIUM, MOVABLE RELATIVE THERETO, AND RECEIVES A PLURALITY OF CONDUCTORS EACH OF WHICH IS PROVIDED WITH A PORTION EXTENDING IN THE DIRECTION OF MOVEMENT OF THE RECORDING MEDIUM, TRANSVERSELY ACROSS THE CORE STRUCTURE IN SPACED RELATION, WITH PORTIONS OF THE CORE STRUCTURE INTERMEDIATE ADJACENT CONDUCTORS FORMING POLE ELEMENTS COOPERABLE WITH SUCH CONDUCTORS FOR EFFECTING MAGNETIC RECORDING ON SUCH A RECORDING MEDIUM, THE POLE ELEMENTS HAVING FLUX DIRECTING AREAS, ARRANGED FOR COOPERATION WITH SUCH A RECORDING MEDIUM, WHICH HAVE A THICKNESS IN THE DIRECTION OF SAID MOVEMENT LESS THAN .5 MIL, AND A WIDTH TRANSVERSE TO SUCH DIRECTION OF MOVEMENT OF LESS THAN 2 MILS, THE SPACING BETWEEN ADJACENT POLE ELEMENTS BEING LESS THAN 2 MILS. THE INVENTION ALSO INCLUDES A NOVEL METHOD OF PRODUCING SUCH A HEAD, IN WHICH A CORE STRUCTURE OF PARAMAGNETIC MATERIAL IS FORMED WITH AN ELONGATED PORTION HAVING AN EFFECTIVE WIDTH CORRESPONDING TO THE DESIRED EFFECTIVE THICKNESS OF SUCH POLE ELEMENTS, THE CONDUCTORS BEING ARRANGED WITH THE PORTIONS THEREOF, TO EXTEND ACROSS THE CORE STRUCTURE, IN ALIGNED LATERALLY SPACED PARALLEL RELATION, AT THE

    SAME PITCH DISTANCE AS THAT OF THE POLE ELEMENTS, WITH THE CONDUCTOR PORTIONS EXTENDING ACROSS THE ELEONGATED PORTION OF THE CORE STRUCTURE IN COOPERABLE RELATION, THE CORSSING PORTIONS OF THE CONDUCTORS BEING SECURED, IN INSULATED RELATION RELATIVE TO ONE ANOTHER, TO THE ELONGATED PORTION OF THE CORE STRUCTURE WITH THE RESPECTIVE CONDUCTOR PORTIONS ADJACENT TO THE CROSSING PORTIONS SECURED IN RIGID RELATION WITH RESPECT TO THE ELONGATED PORTION OF THE CORE STRUCTURE.
