ABSTRACT:
A magnetic bubble Y-bar corner for use at the end of a minor loop. The Y-bar corner includes a Y-bar corner element and a canted I-bar positioned between the Y-bar corner element and each of the two adjacent storage elements in the minor loop. The ends of the arm of the Y-bar corner element are positioned adjacent the apex portions of the canted I-bars. The distance between the ends of the arms of the Y-bar is larger than the distance between the opposing ends of the two canted I-bars. With this corner a bubble propagates in either direction along a path from a minor loop storage element to the end of the canted I-bar and then to the apex portion of the canted I-bar and from there across to the end of the arm of the Y-bar.
