Latest Patents
Among his latest patents, Lairson has developed a "Soft underlayer structure for magnetic recording." This invention presents a magnetic recording medium that features a soft magnetic underlayer structure consisting of two distinct soft underlayers. The first soft underlayer is thick and made from a material that provides low magnetization saturation and high permeability. It can be formed through plating or high-rate sputtering. The second soft underlayer is thinner and made from a material that offers a higher magnitude of magnetization saturation but lower permeability, which can be created using low-rate sputtering. Additionally, the first soft underlayer can be isolated from other layers by an exchange isolation layer, while the second soft underlayer can be exchange coupled to a radial exchange pin layer.
Another significant patent is "Transverse biased shields for perpendicular recording to reduce stray field sensitivity." This method aims to reduce the flux concentrating capacity of a shield in a magnetic read/write head. The shield is positioned to read perpendicular residual magnetic fields on magnetic media. By inducing a transverse magnetic bias field within the shield, the permeability of the shield is reduced in a direction oriented perpendicular to the magnetic media.
