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.

A method of and apparatus for providing single wall self-biased magnetic domains in a film of uniaxial magnetic material. In addition to the conventional uniaxial magnetic film for supporting the single wall domains, a bias film is located adjacent thereto. The material characteristics of the two films and their thicknesses are chosen such that the exchange coupling between the two films provides the effect of an external field for supporting the single wall domains.

The data stored in a coincident block access bubble domain memory with bit-organized chips is encrypted by skewing or permuting selected word bits by predetermined amounts. This is implemented by providing an additional current loop on some or all of the chips which overlies the major loop pattern and has nodes at the similar vector poles of the major loop. The proper energization of selected ones of these additional current loops, under the control of a security key, inhibits or suppresses the advance of the bubble domains in the corresponding major loops for a predetermined number of cycles of the in-plane propagating field, thus skewing the word bits in these chips with respect to the remaining word bits in the unsuppressed chips. Decryption is accomplished by further inhibiting the same major loops for the necessary number of cycles to restore word bit synchronization throughout the memory.

A thin-film disc fabrication method and structure contemplates a sputtered undercoat. An aluminum base is subjected to a fine polishing step, and a relatively thin undercoat is deposited by sputtering. The preferred undercoat is a 0. 3-3 micron layer of nickel-vanadium alloy (on the order of 7% vanadium). The preferred recording layer is a sputtered composite structure comprising a layer of chromium and an overlying layer of a cobalt-chromium alloy. Modulation effects can be substantially eliminated by heating the aluminum base prior to sputtering the nickel-vanadium undercoat, and by oxidizing the undercoat prior to deposition of the overlying layers.
