Abstract
An improved non-data reversing one-way bubble transfer switch for contiguous disks is disclosed. The switch has a conductor arrangement in which one edge of the conductor is substantially concentric with and overlapping with the major loop which is in the form of a plurality of scallops. The major loop extends in a direction substantially transversely to one of the three primary crystallographic axes in the bubble material so as to have a propagation track with a high margin on one side and a low propagation margin on the other side. The tip of a minor loop end portion is aligned substantially concentric with the scalloped concave portion of the major loop. This switch has a maximum bias field margin and a maximum phase margin.
