Latest Patents

Sakaguci's latest patents include a method for manufacturing a thin film head. This invention features a magnetoresistive element that comprises an antiferromagnetic layer, a pinned layer, a nonmagnetic conductive layer, and a free magnetic layer. Additionally, it includes a pair of laminated transverse biasing layers, each containing a nonmagnetic layer, a ferromagnetic layer, and an antiferromagnetic layer. The specific layer thickness of the nonmagnetic layer is crucial for ensuring that the magnetizing direction in the free magnetic layer opposes that of the ferromagnetic layer.

Another notable patent is the MR thin film head with longitudinal-biasing multi-layers of antiferromagnetically-coupled high and low coercivity layers. This invention includes a GMR element formed of an antiferromagnetic layer, a pinning layer, a nonmagnetic conductive layer, and a free magnetic layer. The biasing layers consist of a high coercivity ferromagnetic layer, a nonmagnetic layer, and a low coercivity ferromagnetic layer, which are antiferromagnetically exchange-coupled via the nonmagnetic layer.
