Title: Osamu Tonomura - Innovator in Magnetic Recording Technology
Introduction
Osamu Tonomura, a talented inventor based in Fujisawa, Japan, has made significant contributions to the field of magnetic recording technology. Known for his innovative thinking, he holds a patent that enhances the functionality and durability of disk drive sliders, showcasing his commitment to advancing modern technology.
Latest Patents
Tonomura is credited with a patent for a product known as the "Slider with Spin-Torque Oscillator (STO) and STO Corrosion Monitor." This innovative disk drive slider supports a microwave-assisted magnetic recording (MAMR) write head, which incorporates a spin-torque oscillator (STO) along with a separate corrosion monitor (CM). The CM is designed with a corrosion detection layer made from the same material as the STO's spacer layer, allowing it to effectively monitor corrosion while maintaining performance. This setup ensures that the CM is coplanar with the STO and strategically spaced laterally, exposing it to identical atmospheric conditions as the spacer layer. The detection mechanism relies on measuring the electrical resistance of the CM by detecting current flow within the corrosion detection layer.
