发明名称 Defect-free magnetic stampers/imprinters for contact patterning of magnetic media
摘要 A method of manufacturing a magnetic stamper/imprinter for use in patterning of magnetic recording media by means of a contact printing process, comprising sequential steps of:(a) providing a stamper/imprinter comprising a body of a magnetic material having an imprinting surface including a topographical pattern corresponding to a pattern to be formed in the surface of a magnetic or magneto-optical (MO) recording medium and comprising a patterned plurality of spaced-apart recesses with a plurality of non-recessed areas therebetween, said imprinting surface including a plurality of defects comprising surface blemishes and stains, magnetic particles, and non-magnetic particles;(b) initially removing the surface blemishes, stains, and magnetic particles; and(c) then removing or rendering the non-magnetic particles benign to the contact printing process.
