ABSTRACT:
A mold assembly for forming a replica disk in a disk molding process. The replica disk includes a formatted surface on both sides. The mold assembly includes a disk substrate cavity defined by a first block having a first major surface, a second block having a second major surface, and an outside edge. The first stamper has an outside edge. The first outer holder includes a first holder edge, the first holder edge extends over the outside edge of the first stamper, coupling the first stamper to the first major surface. A second stamper having an outside edge is coupled to the second major surface. A channel is provided in fluid communication with the disk substrate cavity for allowing disk molding material to enter the disk substrate cavity. Further, a stripper mechanism may be located at the outside edge, wherein the stripper mechanism is moveable relative to the first block and the second block.
