ABSTRACT:
A high field contrast magnetic stamper/imprinter for use in patterning of magnetic and magneto-optical (MO) recording media by contact printing, comprises:(a) a layer of a magnetic material having a high saturation magnetization Bsat≧˜1.2 and high permeability μ≧˜5, including a first, topographically patterned surface and a second surface opposite the first surface, the first, topographically patterned surface comprising a patterned plurality of spaced-apart recesses with a plurality of non-recessed areas therebetween, the topographical pattern corresponding to a magnetic pattern to be formed in a magnetic or MO recording medium; and(b) a layer of Ni on the second surface. A corrosion-resistant protective overcoat layer may be present on the topographically patterned surface. A method for manufacturing the stamper/imprinter is also disclosed.
