Abstract
The invention is directed toward techniques for stamping optical data storage disks. A master is first created to include several distinct information regions etched upon a master surface. The master is then used to create one or more stampers. The stampers include a number of distinct stamper regions in locations corresponding to locations of the distinct information regions on the master. The stamper is then used to create a number of first replica disks that include distinct replicated regions. The distinct replicated regions are removed from the first replica disks to define second disks.
