Title: Hermann Deichelmann: Magnetic Storage Inventions

Introduction

Hermann Deichelmann was an inventor associated with BASF Aktiengesellschaft in Ludwigshafen, Germany. His recorded work includes 3 patents, including inventions focused on magnetic thin-film storage and magnetic-domain storage.

Latest Patents

Magnetic Domain Storage Device. This invention describes a ferromagnetic, polycrystalline metal layer with strip-shaped channels of lower coercivity surrounded by areas of higher coercivity. Electrical conductors create, propagate, and detect magnetic domains in the channels. The channels follow a spiral-like path, making at least one full turn across the support. The design aims to increase storage capacity.

Magnetic Thin Film Storage Device. This invention describes a shift-register storage device with a ferromagnetic layer containing lower-coercivity regions surrounded by higher-coercivity regions. Electrical conductors generate the magnetic fields that move domains through the channels. Groups of channels terminate in a shared enlarged area, where domains are propagated individually and consecutively. The simplified geometry supports easier component alignment and automated production, while helping reduce random data-flow errors.
