Abstract
Durable replication tools are disclosed for replication of relief patterns in desired media, for example in optical recording or data storage media. Methods of making such durable replication tools are disclosed, including recording and developing a relief pattern on a selected surface of a support cylinder, creating a durable layer with a complementary relief replica of the pattern, separating the durable layer from the support cylinder. Apparatus are disclosed for fabricating such replication tools, including systems and apparatus for recording a desired relief pattern on a surface of a support cylinder. Also disclosed are electro deposition cells for forming a durable tool sleeve having a desired relief pattern. The replication tool relief features may have critical dimensions down to the micron and nanometer regime.
