ABSTRACT:
A magnetic-bubble memory device comprising a bubble propagation path defined by patterns of magnetically soft material, along which magnetic bubbles propagate in response to an in-plane rotating magnetic drive field. The bubble propagation path has a first track and a second track and a connection for interconnecting the first track and the second track. The first track is defined by conventional propagation patterns, and the second track is defined by known hook-shaped wide-gap patterns or modified wide-gap patterns. The connection includes a connection pattern having one end portion arranged with respect to the terminal pattern of the first track in the same constructional relationship as that between the successive patterns of the first track and another end portion arranged with respect to the terminal pattern of the second track in the same constructional relationship as that between the successive patterns of the second track. Such a bubble propagation track makes it possible to realize a 4 .mu.m period 4 Mb bubble memory.
