Latest Patents

One of his latest patents focuses on barium ferrite magnetic storage media. This innovation describes magnetic storage media that include a multilayer structure, consisting of a substrate, an underlayer with a plurality of underlayer particles, and a magnetic layer with magnetic particles. The magnetic layer is designed to define a saturated magnetization and thickness product of less than or equal to approximately 1.00 memu per square centimeter. The magnetic particles are selected from a group that includes magnetic platelet-shaped particles and those with an aspect ratio of less than or equal to approximately 1.5. This invention aims to minimize interlayer diffusion between the underlayer and magnetic layer, resulting in an improved magnetic recording surface for data storage.

Another significant patent by Sharrock involves techniques for erasing and writing to magnetic storage tape that has a perpendicular squareness greater than 50 percent. This magnetic tape can be biased with a remanence magnetization in any direction, utilizing one or two head systems to create the desired magnetic orientation. The innovation also includes the creation of servo marks with a remanence magnetization that is perpendicular to the magnetic tape, enhancing the efficiency of data writing and erasure.
