Introduction

Heinz Hilgers is a notable inventor based in Mainz, Germany. He has made significant contributions to the field of magnetic recording technologies, holding 2 patents that showcase his innovative approaches.

Latest Patents

One of his latest patents is a process for surface modification of magnetic heads by a reactive gas. This process involves modifying the outermost atomic layer of a substrate, such as a carbon layer with hydrogen atoms, in a plasma chamber. The goal is to covalently bond carbon-fluorine groups, specifically CF.sub.3 groups, to the surface carbon atoms. This method enhances the surface properties, providing high affinity for lubricants while minimizing contamination. It is particularly beneficial for magnetic recording heads and disks.

Another significant patent by Hilgers is a method of increasing the lubricant retention of magnetic disks. This invention describes a two-step curing process for a magnetic layer containing magnetic particles. The first step involves heating the magnetic layer in an inert gas, followed by a second step in a nitrogen atmosphere with added oxygen. This process leads to polymerization and oxidation, resulting in improved lubricant retention through the formation of pores in the magnetic layer.
