Title: The Innovative Mind of Jacques Desserre: A Pioneer in Magnetic Recording Technologies
Introduction: Jacques Desserre, an accomplished inventor from Rambouillet, France, has made significant contributions to the field of magnetic recording technology. With a remarkable portfolio of 11 patents, Desserre has been a driving force in the development of innovative solutions that address the evolving needs of data storage and processing.
Latest Patents: Among his latest inventions is the patent for "Perpendicular Anisotropic Magnetic Recording". This innovative substrate comprises a nonmagnetic foundation on which a thin metal magnetic medium with a negative magnetostrictive effect is deposited. The design ensures that the direction of easy magnetization remains perpendicular to the surface, thus enhancing recording density. To mitigate the magnetostrictive effects, Desserre's invention includes a stack of alternating thin magnetic and nonmagnetic layers, crafted to allow strong magnetic coupling while dampening any strain discrepancies. The specific thicknesses of these layers are meticulously engineered to fall within the range of 150 to 250 angstroms for nonmagnetic layers and 700 to 2000 angstroms for magnetic layers. The application of this patent is primarily within magnetic recording disks, showcasing Desserre's foresight in advancing storage technologies.
Additionally, Desserre has patented a "Magnetic Reading/Writing Transducer for Perpendicular Recording." This device is designed for efficient data writing and reading on perpendicular recording carriers, such as magnetic disks. The transducer showcases a writing pole that operates perpendicular to the recording media, along with a coil that is magnetically coupled to the pole for seamless data operations. The unique configuration of the spiral coil offers improved performance and reliability in magnetic data transmission.
