Latest Patents

Jackie holds a patent titled "Perpendicular magnetic recording medium with single domain exchange-coupled soft magnetic underlayer and device incorporating same." This patent describes a perpendicular magnetic recording disk featuring a single domain exchange-coupled laminated soft magnetic underlayer (SUL). The SUL combines a synthetic anti-parallel coupled SUL structure, which ensures that the product (Mst) of saturation magnetization and film thickness of the middle ferromagnetic layer is less than the sum of the Mst of the bottom and top ferromagnetic layers. The SUL provides a single domain state when subjected to a post radial field reset process. This innovation achieves both robustness of stray fields and low permeability while maintaining excellent corrosion resistance and cost-effective manufacturability.
