Abstract

In this paper, we report a stable processing method to farbricate the nickel disc and polycarbonate(PC) disc with massive character code and address code in a ϕ120mm master disc. Currently, the optimum laser intensity is found to be 45% for exposure step. The micropore size remains the same size during the electroplating indicating the excellent stability and reliability of the process. In addition, the demolding process during the production of optical disc is smooth due to the controlled angle between photoresist and nickel surface. However, the height of microstructure boss on the optical disc after injection molding is about 10-15nm smaller than we expected.
