Title: Innovations of Omar U Need, III
Introduction
Omar U Need, III is a prominent inventor based in San Jose, CA. He has made significant contributions to the field of magnetoresistive sensors, holding a total of 6 patents. His work has advanced the technology used in magnetic recording data storage systems.
Latest Patents
One of his latest patents is titled "Magnetoresistive spin valve sensor having a nonmagnetic back layer." This invention describes a magnetoresistive read sensor that utilizes the spin valve effect. The sensor's read element consists of two adjacent ferromagnetic layers separated by a nonmagnetic metallic layer. A layer of nonmagnetic electrically conductive material is deposited adjacent to one of the ferromagnetic layers, forming a back or conduction layer that provides a low resistance path for conduction electrons. The design allows for effective blocking of conduction electrons with antiparallel spins while permitting those with parallel spins to pass through.
Another notable patent is "Magnetoresistive sensor with improved ferromagnetic sensing layer." This invention enhances the performance of magnetic recording data storage systems by utilizing a laminated layer of two ferromagnetic films that are antiferromagnetically coupled. The selection of the thickness of the nonmagnetic coupling film allows the ferromagnetic films to rotate as a single unit in response to external magnetic fields. This innovation can be applied in both anisotropic magnetoresistive (AMR) sensors and spin valve magnetoresistive (SVMR) sensors.
