Abstract
A nonmagnetic substrate is shown having a magnetic film that has been separated into a grid-like pattern of spaces to form quadrilateral magnetic elements. The spaces are filled with conductors arranged generally in X and Y directions. Each quadrilaterally shaped magnetic post element has a first and second region of low anisotropy material compared to the high anisotropy material of the magnetic film. The first regions of low anisotropy material are located in one corner of the quadrilaterally shaped post elements while the second regions are located in the corner opposite the first regions. Alternate columns of magnetic post elements have the first and second regions of low anisotropy material in opposite corners defined by a first diagonal, while the remaining columns have the low anisotropy material in corners defined by the second diagonal. This arrangement permits redundant switching of each magnetic post element.
