摘要： A magnetic bubble domain system in which magnetic bubble domains travel along propagation tracks or paths from one location to another, the complexity of the system being such that individual magnetic bubble domain paths are required to cross each other. A magnetic bubble track crossover element is included in the magnetizable overlay pattern defining the respective magnetic bubble domain propagation paths, being located at the intersection of a pair of such propagation paths so as to regulate the flow of individual bubbles from the respective propagation paths in crossing the intersection to remain undisturbed in continuing their respective courses along the same path. The crossover element is made of the same magnetizable material of the remainder of the magnetizable overlay pattern, e.g. permalloy, as provided on a layer of magnetic material of a type suitable for the propagation of magnetic bubble domains therein. An in-plane rotating magnetic field within the plane of the magnetic layer on which the magnetizable overlay pattern is disposed causes propagation of magnetic bubble domains along different tracks or paths as it revolves. The magnetic bubble domains on different tracks pass through the crossover element intersection at different drive field orientations, free from interference with each other, thereby minimizing the interaction between bubbles from different tracks.
