ABSTRACT:
A large capacity bubble memory device using a basic storage cell design. The basic storage cell is repeated, typically in matrix form, on a suitable bubble domain structure. The cell design is arranged so that interconnecting elements between respective cells permit magnetic bubble domains to be transferred between cells. The cells include redundancy features so that the cells can be interconnected to form a large capacity storage loop.
