Zusammenfassung:	Disclosed herein are data storage media and methods of making the same. The data storage media, comprises: primary surface features disposed on at least one side of said data storage media; and secondary features superimposed over at least a portion of said surface features. In one embodiment, the method for manufacturing the data storage media comprises: disposing an identifier layer onto a surface of a stamper, said stamper having primary surface features on a first side of said stamper opposite said identifier layer; forming secondary features on an exposed surface of said identifier layer; installing said stamper into a mold; injecting a molten plastic material into the mold, wherein said molten plastic physically contacts said first side; cooling said plastic to form said data storage media, such that a positive image of said primary surface features and of said secondary features are formed into at least a portion of a surface of said plastic; and releasing said data storage media from said mold.
