Latest Patents

Johns' latest patents include "Nitrogen-containing materials for wear protection and friction reduction" and "Process for production of magnetic media." The first patent describes a hard protective material and method for forming a medium with the formula C.sub.x N.sub.y. This medium can be applied as a protective film on magnetic recording disks using a sputtering apparatus, such as a magnetron apparatus. The properties of the films are enhanced by controlling the nitrogen content through the bombardment of the substrate by electrons, resulting in a textured nanoscale morphology that improves lubricant retention. The second patent outlines a process that involves an oxidizing treatment prior to the electroplating of the magnetic layer in thin-film magnetic recording media. This treatment is designed to achieve high coercive force and low media noise.
