Abstract
Abstract Apparatus is provided using as an integral portion thereof a confined array (such as a lattice) of interactive elements, the interactions among which are largely determinative of the positions of the interactive elements since there is a minimum of position determining structure for the elements within the area of confinement. Magnetic elements are suitable interactive elements, and in particular embodiments are shown using magnetic bubble domains. Structure is provided to form lattice arrays of interactive elements, to confine the lattice arrays, and to access elements outside and within the lattice array. In addition, various structures are provided to code the interactive elements for storage of information, and reading devices are provided to detect the information state of the interactive elements when these elements are coded. Various types of lattices and interactive elements can be used.

An apparatus comprising: means for generating magnetic elements which can interact with one another, means for controllably confining said elements in a region where said elements are free to move with respect to one another to determine their positions within said region of confinement, manipulation means for controllably manipulating said magnetic elements in said region of confinement, said magnetic elements being magnetic bubble domains which have different properties, said different properties being different bubble domain wall magnetization states, and means for detecting said different bubble domain wall magnetization states.
Claim 106
Independent Claim
73 words
An apparatus comprising: a magnetic medium in which magnetic bubble domains can exist, confinement means for confining said domains in a region of said medium where the positions of said domains with respect to each other are substantially determined by interactions between said domains in said magnetic bubble domains having different properties, means for moving said domains in said region of confinement, and means for detecting said different properties of said bubble domains.
Claim 107
Independent Claim
73 words
An apparatus comprising: a magnetic medium in which magnetic bubble domains can exist, confinement means for confining said domains in a region of said medium where the positions of said domains with respect to each other are substantially determined by interactions between said domains in said magnetic bubble domains having different properties, means for moving said domains in said region of confinement, and means for detecting said different properties of said bubble domains.
Claim 108
Independent Claim
104 words
An apparatus comprising: a magnetic medium in which magnetic bubble domains can exist, confinement means for confining said domains in a region of said medium where the positions of said domains with respect to each other are substantially determined by interactions between said domains in said region to produce an array of said domains having multiple rows of said domains, means for moving at least one row of domains within said region of confinement to positions corresponding to those occupied by domains which were initially spaced at least two rows from the domains in said at least one row, in said region of confinement.
