Abstract
A technique for accessing interactive elements, such as magnetic bubble domains, which are in confined arrays where the elements are located with respect to one another in accordance with interactions therebetween. In order to improve the access time to any element within the confined array, the elements are removed in a direction substantially transverse to the direction of their translational movement within the confined array. In particular, this technique is useful for accessing columns of magnetic bubble domains in a lattice array of bubble domains. A bubble pump device is utilized to remove the interactive elements from the array. The bias field conditions for this pump propagation structure are the same as for the lattice. Bubble domains can be removed from the lattice and returned to their positions within the lattice.
