Claim:
A method for manufacturing a data-storage medium having a final pattern of pits and lands, the method comprising: (a) applying a layer of a uncured, light-curable material to a substrate; (b) illuminating selected regions of the layer with material-curing light using an optical mask corresponding to an initial pattern of pits and lands different from the final pattern to cure portions of the material corresponding to the initial pattern of pits and lands; (c) illuminating, separate from the illumination of step (b), one or more selected regions to convert at least one of (i) a selected pit region into a land region and (ii) a selected land region into a pit region, wherein the selective illumination ensures that the completed data-storage medium, having the final pattern of pits of lands, is operable in a player apparatus; (d) removing uncured portions of the material from the substrate to create lands corresponding to the cured portions; and (e) completing the manufacturing of the data-storage medium having the final pattern of pits and lands.
