A lattice file using magnetic bubble domains which are arranged in a regular lattice which is moved or expanded to allow different operations, without requiring the need for bubble domains to be entered into or removed from the lattice. This distinguishes from prior lattice files where new information is entered into the lattice and information to be read is removed from the lattice. In a first embodiment, the inherent stability of the lattice is utilized by providing high density lattice for storage and a relaxed (expanded) lattice for operations such as read and write. Thus, the spacings between the elements in the lattice are changed but their relative positions in the lattice are not changed. In a second embodiment, the lattice is shifted without substantially changing the inter-element spacing and information is written and read from bubble domains magnetostatically coupled to the lattice domains. In both embodiments, the lattice is retained so that elements do not have to be brought into and out of the lattice for the performance of memory and storage functions.
