Latest Patents

One of his latest patents is for a magnetic head with alternately laminated (110)-orientation-inducing non-magnetic underlayers, magnetic layers, and discontinuous insulating layers. This innovative design includes a write magnetic pole characterized by a magnetic film formed through the alternation of magnetic layers, primarily composed of iron (Fe) and cobalt (Co), along with insulating layers that are discontinuous films. This construction allows for the formation of a write magnetic pole with a high Bs value and high permeability, enabling recording onto high-density media with a high coercive force.

Another significant patent involves a magnetic film for a magnetic head, which includes an FeCo layer that restrains data erasure by magnetic fields leaked from a magnetic pole. This film exhibits high saturation magnetic flux density and soft magnetism, allowing for high recording density. The magnetic film comprises a non-magnetic layer made from materials such as Ru, Rh, Ir, Cr, Cu, Au, Ag, Pt, and Pd, along with a magnetic layer containing Fe and Co. The anisotropy magnetic field is set at 0.8 kA/m or more, enhancing its performance.
