Title: Mathijs De Jongh: Innovator in Optical Scanning and Magnetic Head Technologies

Introduction

Mathijs De Jongh is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the fields of optical scanning and magnetic head technologies. With a total of 3 patents to his name, De Jongh's work reflects a commitment to innovation and advancement in technology.

Latest Patents

One of his latest patents is an optical scanning device designed for scanning an optical record carrier that comprises an information layer. This device incorporates crosstalk cancellation using a phase modulating element to generate a non-rotationally-symmetric phase profile in a subsidiary radiation beam. The phase profile varies with an azimuthal angle measured about the optical axis of the beam portion, introducing successively different phases in at least five locations at successive azimuthal angles. This innovative design ensures that the subsidiary beam spot has an intensity distribution that overlaps with that of the side-lobe of the main beam spot.

Another significant patent is for a magnetic head that features a wear-resistant layer and a method of manufacturing such a magnetic head. This magnetic head includes a head face composed of thin layers and a transducing element. The head face is designed with a first layer made of a material that is more sensitive to corrosion than other materials present. This first layer is complemented by a second layer of a wear-resistant material, which is less sensitive to corrosion, ensuring durability and efficiency in cooperation with magnetic tape.
