Claim:
A method for manufacturing a data-storage medium having 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 to cure portions of the material corresponding to the selected regions to generate at least one false-pit or false-land region; (c) separately selectively illuminating the false-pit or false-land region to convert (i) the false-pit region into a land region or (ii) the false-land region into a pit region; (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, wherein: step (a) comprises applying the layer of material to a first substrate; and step (d) comprises: (1) removing uncured portions of the material from the first substrate to create lands corresponding to the cured portions on the first substrate; and (2) transferring the lands from the first substrate to a second substrate by applying pressure between the first and second substrates.
