ABSTRACT:
In a dual-conductor type current-access magnetic bubble memory, a major loop is provided with a zigzag propagation path through which the major loop is connected with a plurality of minor loops, and transfer gates between the major and respective minor loops are formed by juxtaposing in parallel and partially superposing a pair of apertures of the same pattern upon each other and are surrounded by a gate control conductor, whereby bubbles can successively be transferred between the major and minor loops with a current sequence for normal propagation in the major and minor loops when a gate current is applied to the gate control conductor.
