Abstract

A bubble domain lattice system in which information exists as the presence and absence of bubble domains. A lattice exists in a conveyor layer and lattice bubble domains are coupled (magnetostatically or by exchange forces) to information bubble domains in another magnetic layer (information layer). These information bubble domains are coded in accordance with their presence or absence in the information layer. When the bubble lattice domains in the conveyor layer are moved, corresponding bubble domains in the information layer move in a similar manner, due to the magnetostatic coupling. Consequently, the high density advantages of a lattice arrangement are achieved in the present system, while coding of information is achieved without having to require different types of magnetic bubble domains.
