Development of a System for Data Storage on Machine Components
Authors: Prof. Hans Heinrich Gatzen, Mr. Karl Hans Wu
Abstract
A new approach for data recording through the entire manufacturing process is to apply the magnetic recording
technology for the storage of information on components themselves. Such a system capable of magnetic recording
consists of a device for data recording, one for data retrieval, and a magnetic storage medium. For recording the data,
the basic approach of inductive writing is used, using a recording head creating a magnetic flux, which performs the
data storage. To ensure the application in a machine environment, a remote readout from a distance is desirable. For
this purpose, the Magneto-optical Kerr Effect (MOKE), which senses the direction of the magnetization of a
reflecting surface, is used. The storage medium, which will be used, is magnetic magnesium, a magnesium filled
with hard magnetic particles. To allow a magneto-optical readout based on MOKE of a storage medium containing
magnetic particle, the bulk storage material is covered with a soft magnetic layer. This “keeper layer†is necessary to
generate a homogeneous magnetic and reflective surface, which are features not provided by the magnetic
magnesium. This paper describes the developing and testing the magnetic recording system. The tests were done on a
preliminary material, which has the same magnetic properties like magnetic magnesium.
