Latest Patents

Mitsuo Masuda holds a patent for a substrate for a perpendicular magnetic recording medium. This invention includes a soft magnetic underlayer that serves as a backing layer for the recording medium. The substrate is constructed with a nonmagnetic base made of an Al–Mg alloy. The soft magnetic underlayer is formed from a Ni–P alloy, which contains phosphorus in a range of 0.5 wt % to 6 wt %. This layer is created through electroless plating on the nonmagnetic base. Additionally, the substrate can feature a nonmagnetic underlayer formed by electroless plating prior to the soft magnetic underlayer. The surface of the soft magnetic layer is textured using free abrasive grains to enhance its properties. Following this, a nonmagnetic seed layer, a magnetic recording layer, and a protective layer can be applied through sputtering techniques. A soft magnetic supplemental layer may also be added before the seed layer is formed.
