Foreign and domestic accomplishments in magnetic bubble device technology

Abstract

This document assesses the status of magnetic bubble technology as displayed by non-U. S. research and manufacturing facilities. Non-U. S. research and U.S. accomplishments are described while both technical and economic factors are addressed. Magnetic bubble devices are discussed whenever their application could impact future computer system design. Generally the magnetic bubble device can be applied to a computer system as a peripheral mass memory. Magnetic bubble devices are produced from either synthetic garnet or amorphous materials rather than from familiar silicon material. The document contains a significant bibliography to support certain main points which are supplemented by information supplied by the library of the Information Technology Division (ICST-NBS) and from private interviews with various U.S. technical experts.
