Title: Mark Anthony Shows: Innovator in Magnetic Recording Technologies
Introduction
Mark Anthony Shows is a prominent inventor based in Fremont, CA (US). He holds a total of 10 patents that showcase his contributions to the field of magnetic recording technologies. His innovative work has significantly advanced the capabilities of data storage media.
Latest Patents
Among his latest patents, Shows has developed a thin-film magnetic recording media with a dual intermediate layer structure designed for increased coercivity. This technology involves ion beam-deposited, nitrogen-doped carbon-hydrogen (C:H) films that exhibit substantially lower resistivities compared to undoped counterparts. These films are suitable for use as hard, abrasion-resistant overcoat layers for magnetic recording media, such as hard disks. The nitrogen content in these films is carefully controlled to range from about 5 to about 25 atomic percent by adjusting the ratio of hydrocarbon to nitrogen gas flow. This innovation reduces the tendency for charge build-up during hard disk operation, enhancing performance.
Another significant patent involves a method and apparatus for multilayer deposition utilizing a common ion beam source. This method allows for the ion beam deposition of defect-free multilayer coatings, particularly carbon-based protective overcoats for magnetic and magneto-optical data recording media. The inventive approach employs a single ion beam source for multiple layers, minimizing cross-contamination and reducing equipment costs and size by eliminating the need for separate ion beam sources for each layer.
