Latest Patents
One of Hu's latest patents is the Thin Laminated Single Pole Perpendicular Write Head. This invention addresses the issue of large shape anisotropy in single write poles, which results in a substantial remnant field when not actively writing. Hu's design eliminates this problem by utilizing a three-layer laminate structure. In this configuration, two ferromagnetic layers are separated by a non-magnetic or antiferromagnetic coupling layer. The strong magnetostatic coupling between the outer layers ensures that their magnetization directions are automatically antiparallel, unless overridden by a more powerful write field. This innovative approach leaves the structure with a low net magnetic moment, enhancing its efficiency. The thickness of the middle layer is a critical factor that must be carefully controlled to achieve optimal performance.
