A new method for making patterned magnetic storage media with magnetic and substantially non-magnetic zones utilizes a selective oxidation processes. Selective oxidation is achieved by subjecting a magnetic layer to an oxygen plasma through voids in a patterned mask. A high resolution patterned...http://www.google.fr/patents/US6168845?utm_source=gb-gplus-shareBrevet US6168845 - Patterned magnetic media and method of making the same using selective oxidation
