Abstract

The basic elements of a magnetic bubble device are laminated. A spacer conductor pattern layer is formed on the same plane as a control conductor pattern layer interposed between a magnetic film which forms and holds magnetic bubbles and a propagation circuit pattern layer adapted to control the magnetic bubbles so as to make substantially uniform the distance between the propagation path and the magnetic film.
