Process principle for the production of sintered dynamic component-inherent data storage

Abstract

This paper presents a method for the magnetic data storage on the surface of gentelligent components.One key issue is the possibility to store customers' data on components dynamically and to read it out later on. The data storage is carried out magnetically and is demonstrated on a high-speed milling head. As such components are mostly made of light materials without magnetic properties; areas for the data storage on the surface must first be defined. Sintered components made of Mg and of hard magnetic particles have the potential to meet these requirements.

Material-inherent Data Storage Using Magnetic Magnesium-cobalt Alloys

“…The data track was constantly written in the direction of the axis of symmetry, and thus, along the areas of different cooling rates. These data tracks could be read out with a GMR-sensor as is explained in [7]. The results of this evaluation are measured voltages in relation to the sample's length.…”
