A first magnetization level can be written to a selected region of said recording layer by applying a first write field to the grains of said region to form a “spin-up” magnetization in the grains of said region. A second magnetization level can be written by applying a second opposite write field to selected grains of said region to form a “spin-down” magnetization. At least a third intermediate magnetization level can be written by applying a weaker or alternating write field to grains of said region to form an intermediate magnetization comprising a mixture of spin-up and spin-down grains. By such method, said region may comprise a data bit capable of storing 3 or more units of information corresponding to the number of separate magnetization levels employed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"3DMR media with multiple write field levels","description":"A three-dimensional magnetic recording media can consist of a single recording layer configured with three or more separate magnetization levels.
