ABSTRACT:
A method of manufacturing a stamper/imprinter for use in patterning of a recording medium, comprising sequential steps of:(a) providing a permanent master comprising a body of a substantially rigid material having a surface with a topographical pattern formed therein comprising a patterned plurality of spaced-apart recesses with a plurality of non-recessed areas therebetween, the topographical pattern corresponding to a pattern to be formed in a recording medium;(b) forming a layer of a substantially rigid material over the surface of the permanent master with the topographical pattern formed therein;(c) separating the layer of a substantially rigid material from the master, the layer of a substantially rigid material having an imprinting surface with a topographical pattern formed therein replicating the topographical pattern of the permanent master; and(d) repeating steps (b) and (c) multiple times with the permanent master provided in step (a) to form a plurality of stampers/imprinters.
