Abstract

The purpose of the experiment was to find the optimum replication process for making submicron structured DVD-RAM substrates with superb optical and geometrical properties. The optimum processing conditions were presented. It was found that the birefringence, which is regarded as one of the most important optical properties for an optical disk, was very sensitive to the mold wall temperature history. Also, the integrity of the replication, represented by the land-groove structure, and the radial tilt were influenced most by the mold temperature and the compression pressure.
