Overview of testing and manufacturing processes for optical recordable media: industrial view

摘要

We shall give an overview of the several off-line testing methods which are recently developed. The specifics some of the methods will be described in details. Relations between the tested parameters and manufacturing process will analysed. Several indications will be described for substrates optimization, evaluation of the dyes for recordable media, control and correction of the dye distribution on the blank substrates. Relation of the dye coating with the process conditions will be described. Important process steps and their evidence in the various tested parameters on the ready media will be analysed. Further consequences of the manufacturing technology onto the performance of the final media will be discussed.
