Fabrication of patterned Pt/Co multilayers for high-density probe storage

Patterned media may offer a route to densities beyond 1 Tb/in2 in future magnetic storage systems. Two approaches for media patterning, interference and natural lithography, that offer advantages over conventional approaches, such as optical and electron beam lithography are evaluated. Both approaches are quick, inexpensive and have the ability to produce arrays of nanometre-sized magnetic islands over large areas.
