DEVELOPMENT OF DVD-R PROCESS BASED ON ORGANIC MEDIA

Abstract

Polymers seem to provide a solution to almost every deed in life, from preparing daily commodities to the highly sophisticated, artificial heart valve. Due to the availability of such special kind of properties including high heat strength, very high refractive index and excellent mechanical properties in polycarbonate, it is possible the existence of optical disc. Till the date the performances and the applications point of view there are lots of study done in this field but the processing technicality involve in the manufacturing of DVDR via various processes still to revealed. The injection moulding of digital video disk substrates requires the selection of over forty process parameters to ensure the satisfaction of over twenty quality attributes. The present work develops a methodology for process characterization through empirical models, termed transfer functions. The transfer functions can then be used to optimize a process, compare different processing systems, or p...
