ABSTRACT:
An improved magnetic memory system in which binary data are stored as cross-tie, Bloch-line pairs, which are serially propagated downstream along a cross-tie wall and a magnetizable layer by appropriate drive fields. The magnetizable layer is configured into a data track whose two mirror-image, opposing edges are formed into patterns of asymmetrically shaped edges which form successive narrow portions, or necks, with wide portions therebetween, and which shaped edges are formed about the geometric central line of the data track. The cross-ties are structured in the data track by opposite-edge necks at which the ends of the cross-tie are magnetically stable. The improvement comprises:
