DOMAIN TRACK TRANSFER DEVICE USING AUXILIARY IN PLANE UNIDIRECTIONAL FIELD

摘要

Magnetic device comprising at least one thin layer of a magnetisable material which has a preferred direction of magnetisation substantially at right angles to the surface of the layer and domain positioning structure. In the layer magnetic domains are maintained, moved, and annihilated by magnetic fields one of which is situated substantially in the plane of the layer and does not change direction and under the influence of which the domains are moved parallel to the axis of the magnetic field.
