A method for forming a stamper used in the manufacture of CDs, DVDs, and other types of optical disks comprises forming a substrate by rolling. A layer of material is deposited (e.g. by plating) onto the substrate. Thereafter, a resist layer is formed on the layer of material and patterned. Because the substrate is formed by rolling, it is relatively inexpensive to form the substrate to a desired thickness. Because the layer of material is formed by deposition (e.g. plating), it is relatively inexpensive to ensure that the layer has a very smooth surface (i.e. without necessitating a great deal of polishing).
