Abstract
A magnetic bubble domain memory system having a first bubble domain path composed of Permalloy pattern elements, and a second bubble domain path composed of a current conductor is disclosed. Separate drives are associated with each of the paths, so the advantages of both types of domain propagation can be combined on a single memory chip. The first and second paths are interconnected, so transfer of domains between paths is possible.
