Paper Abstract

The process of replication, such as molding, clamping, injection, metalizing, even extrusion and printing, put an important impact on the quality of the finished DVD discs. They are crucial to duplicator, but not so easy to detect by conventional analysis methods provided by current commercial off-line tester. We introduce a data-analysis method to enlarge the effects of replication process on the disc parameters, by means of eliminating the disturbance from pre- replication process. This method is named RES (Remainder Elimination of the effect Stamper) parameters. An example is given to show the status of disc's edges affected by molding, and the selection of different molding patterns is analyzed.
