摘要： In a display unit utilizing magnetic bubbles, selective extinction of the magnetic bubbles in a matrix results in a pattern of letters and/or images which are combinations of the magnetic bubbles as picture elements. The present display unit has in-plane anisotropic areas each of which has an easy magnetization axis parallel to the surface of the magnetic bubble material thin film produced by attaching the magnetically soft thin film on the magnetic bubble accommodation spaces in the magnetic bubble material thin film or by ion-implanting into the given spaces of the magnetic bubble material garnet. Therefore, according to this invention, the domain walls of the magnetic bubbles are attracted to said in-plane anisotropic areas and securely held at predetermined picture element positions. And the additional in-plane anisotropic areas may be formed at desired locations where the domain walls of the expanded magnetic bubbles should exist, or locations extending from the bubble collapse diameter to the expanded diameter. This makes possible to obtain expanded magnetic bubbles on picture display, and hence minimize the ratio of the mutual distance of the bubbles to the bubble diameter, improving the quality of the picture displayed.
