“…Bobeck and Fischer (1959) had suggested the propagation of a magnetic domain pattern along the axis of a fine ferromagnetic wire as a way of realising a memory using a stationary magnetic material and a moving magnetic data pattern. Broadbent (1960) took this idea further by considering the possibilities of moving domains around in the plane of a thin ferromagnetic film of a material like permalloy, having an easy direction of magnetisation in the plane of the film. Smith (1961) came up with the idea of using not the domains themselves but the domain walls to represent the binary data, and showed not only how these data could be moved inside a stationary medium but also how logical operations might be implemented.…”

The invention of a number of interesting magnetic bubble domain devices over the past eighteen years, for computer memory, data-flow data processing and optical image processing, has brought many new and interesting problems to the attention of physicists. These problems, in materials, particularly crystal growth, in magnetic domain dynamics, in the physics of ion implantation, in complex magnetic field calculations and in magneto-optics are reviewed and discussed. It is concluded that we have here a particularly significant example of the interaction between technology and science.
