A mold and a process for use in producing data storage articles such as single substrate double-sided disks. In one configuration, a mold for manufacturing a substrate includes a stamper, at least one holder having an interface with the stamper, and a vacuum line for applying a retention force to maintain the interface between the holder and the stamper. In another configuration, the mold includes a demolding line for applying a demolding force to the substrate to aid in separating the substrate from the stamper. The various embodiments of the present invention provide, among other things, easier and faster stamper changeover, substrates and final data storage articles having improved process indicia such as thickness, flatness, inner and outer diameter, and concentricity, and facilitates production of single-substrate double-sided disks.
