A method of making a stamper for use in a data storage disk molding process. The method includes making a first stamper including the steps of providing a stamper body having an information layer thereon. The information layer is covered with a first metal layer. A second stamper is made from the first stamper, which includes the steps of covering the first metal layer with a second metal layer to form a stamper assembly, wherein the first metal layer and the second metal layer are bonded together. The first metal layer and the second metal layer are removed from the stamper assembly to form the second stamper, wherein removal of the first metal layer and the second metal layer is nondestructive to the information layer. In one application, the first metal layer and the second metal layer are made of nickel.
