Title: Ulrich Kuenzel: Innovator in Magnetic Technologies

Introduction

Ulrich Kuenzel is a notable inventor based in Kusterdingen, Germany. He has made significant contributions to the field of magnetic technologies, holding a total of 5 patents. His work primarily focuses on advancements in magnetic head sliders and composite magnetic disks.

Latest Patents

One of his latest patents is a method of making magnetic head sliders. This innovative process involves the anodic oxidation of highly pure aluminum substrates. The surface of the substrates is covered with a mask that leaves specific zones exposed for the formation of rails. By anodically oxidizing the aluminum in these exposed regions, rail layer regions of oxide are created. After removing the mask, these regions can serve as an etching mask to create recessed areas between the rails through chemical wet etching.

Another significant patent is for a composite magnetic disk with silicon and silicon carbide substrates. This invention pertains to a composite magnetic disk designed for magnetic recording. It consists of an annular core made of polymeric material, bonded to at least one disk of reaction-bonded silicon carbide, which features a magnetic recording layer on its outer surface. The processed SiSiC disk surface exhibits optimal planarity and smoothness, making it suitable as a magnetic disk substrate. Additionally, this material has a low density and a remarkably high specific modulus of elasticity, allowing for higher revolution speeds than previously achievable with aluminum-magnesium alloy disk substrates.
