摘要

An apparatus for the controlled generation of coded bubble magnetic domains having one of two known wall states in a bubble domain support means, the apparatus comprising: a flat magnetic layer coupled by exchange to the normal oriented magnetization of the medium bubbles; means for nucleating bubble domains in the bubble medium, below said layer; means for generating in said layer a unipolar magnetic field in a plane; and means for activating said field generating means in a plane, or not activating them, while activating said nucleation means, according to one of two required wall states of the resulting bubble domain.
