Jochen Schneider

Title: Jochen Schneider: Innovator in Magnetic Materials

Introduction

Jochen Schneider is a notable inventor based in Gaertringen-Rohrau, Germany. He has made significant contributions to the field of magnetic materials, holding a total of 2 patents. His work focuses on innovative solutions that enhance the performance and functionality of magnetic recording technologies.

Latest Patents

One of Schneider's latest patents is for a magnetic disk substrate with a core of synthetic material. This substrate employs an annular core made of synthetic material, with thin metal foils bonded to opposite faces. These metal foils are designed to receive a magnetic recording material, forming a magnetic recording structure. To ensure the integrity of the outer surfaces, a thin, soft, deformable layer, such as copper, is applied to the inner surfaces of the foils. This layer prevents irregularities in the core faces from affecting the performance of the magnetic recording disk.

Another significant patent by Schneider is an apparatus for measuring the magnetostriction constant. This invention provides a direct method for measuring the magnetostriction constant of soft magnetic and isotropic magnetic materials. The apparatus utilizes a cantilevered thin film sample that is clamped at one edge. When subjected to a magnetic AC field, the sample's free end deflects and oscillates, allowing for precise measurement of the resonance amplitude using a laser beam and a position-sensitive photodiode.
