Abstract:
1. An apparatus for printing maxels into a magnetizable material, the apparatus comprising: a magnetic print head comprising a flat metal conductor having a plurality of layers forming an inductor coil and a hole extending through the plurality of layers, said magnetic print head configured to generate a magnetizing field having a high magnetic flux density in and near said hole and a low magnetic flux density elsewhere when a current is applied to said magnetic print head; a first circuitry that causes at least one of a magnetizable material and the magnetic print head to move to position said hole of said magnetic print head adjacent to a first location at a surface of said magnetizable material where a maxel is to be printed; and a second circuitry that interacts with said magnetic print head to print a first maxel at the first location at the surface of said magnetizable material, the first printed maxel being associated with a first polarity and a second polarity, wherein the first polarity associated with the first printed maxel is substantially exposed at the surface of said magnetizable material but the second polarity associated with the first printed maxel is not substantially exposed at the surface of said magnetizable material.
