Process and quality control of recordable disc

摘要

The key to control the disc quality is to find the relationship between process parameters and the disc electrical capabilities. This is done in two steps: first step is from process parameters to physical parameters, second step is from physical parameters to electrical parameters. While the first step is based upon test experiments and process analysis, the second step is based upon simulation. In this paper, we apply a simulation model to determine electrical parameters from measured physical parameters of a recordable disc before recording and after recording. Further, we extend the model on dual-layer DVD-R disc.
