摘要

An apparatus for and a method of propagating bubble domains is disclosed. The apparatus includes a memory plane that is comprised of a non-magnetic support member upon which are formed a bubble domain layer and at least one stripe domain layer. The stripe domain layer has a set of relatively-narrow, periodic, potential well generating fixed stripe domains provided therein while the bubble domain layer has a set of relatively-wide, parallel, potential well generating fixed guidance channels provided therein that are oriented orthogonal to the parallel set of stripe domains in the stripe domain layer. Bubble domains are concurrently entered, in parallel, at one end of the memory plane in selected ones of the guidance channels. A periodic amplitude modulated bias field of frequency F propagates each of the bubble domains along the associated guidance channel from adjacent to next downstream adjacent stripe domain and thus through the memory plane at the frequency F.
