Abstract

PURPOSE: To make it possible to duplicate bubbles by adequately transferring bubbles from a memory loop to a read loop by arranging a control pattern electrode at a fixed position while the memory loop and read loop are set with mountain parts and valley parts opposed mutually.
CONSTITUTION: Memory loop 1 and read loop 2 are opposed at an interval and between the both, electodes 4W6 are arranged. Then, loops 1 and 2 are so arranged that mountain part (a) will opposite to valley part (b') and valley part (b) will oppose to mountain part (a'). Respective electrodes 4W6 are connected by connection part 7 at interval part positions of respective loops. Bubbles 3 on loop 1 are moved by revolving magnetic field HR. Bubbles are elongated extending over respective loops and cut off by a current in the direction from electrodes 4W6. Consequently, bubbles are divided into those on loop 1 and on loop 2, thereby realizing the duplication of bubbles.
