Latest Patents
Fred Y Lieu holds a patent for a "Corrosion resistant thin film head assembly and method for making." This invention involves a slider element that includes a thin film transducer deposited onto a slider along at least one of the rails forming the flying air bearing surface with magnetic media. The patent details a process where a portion of the end tips of the pole pieces and gap of the thin film inductive transducer, along with a portion of the slider rail adjacent to the transducer, is etched using a sputter etching process. A layer of passivation material, such as chromium, is then sputter deposited into the etched portion, ensuring that the leading portion of the rail protects the passivation material from wear. This innovative approach prevents corrosion of the iron-nickel alloy that comprises the pole tips of the transducer.
