Latest Patents
Speriosu holds a patent for a method titled "Two step resetting of magnetization of spin valve read head at the row." This invention provides a method for resetting the magnetization of the pinned and hard biasing layers of a spin valve read head at the row level. In the first embodiment, a first magnetic field is applied substantially perpendicular to the air bearing surface (ABS) at room temperature, setting the magnetic moment of the pinned layer perpendicular to the ABS. This is followed by applying a second magnetic field parallel to the ABS to set the magnetic moments of the hard biasing layers. The second embodiment includes resetting the antiferromagnetic pinning layer by heating it with a current pulse, allowing for localized heating adjacent to the pinning layer.
