ABSTRACT:
Improved magnetic bubble memory operation is achieved with an asymmetric half-disc design for a propagate pattern operative to move the bubbles in a "field-access" mode of operation. The pattern ensures the continuous presence of a elongated supportive magnetic pole geometry for the bubbles during operation.
