Direct growth of Bit Patterned Media — The template effect

Abstract

Template assisted direct growth of bit patterned media (TG BPM) is a novel alternative approach of producing bit patterned media (BPM). Unlike conventional BPM, TG BPM directly grows the magnetic bit patterns with oxide bit boundaries by co-depositing magnetic alloy and oxide materials onto an assisting template. In this work, TG BPM samples were deposited on different templates and the template influence on growth mechanism was studied. A functioning high density (1 TD/in2) TG BPM with excellent microstructure and magnetic properties are demonstrated.
