As successors to the familiar DVD formats, Blu-ray Discs and High Density DVDs (HD-DVDs) operate with blue laser light and can each store up from 15 to more than 100 gigabytes, depending on the number of used information layers. This massive leap in storage capacity was to meet the demand to store an entire feature film in the new High-Definition (HD) resolution, on one disc. To take optical data storage (ODS) on to the next generation, thel manufacturers have decided in favor of Makrolon®, the polycarbonate from Bayer MaterialScience AG. Apart from technical requirements, optical disc manufacturers attach great importance to the use of just one material for the production of all formats, in order to simplify logistics and keep investment costs to a minimum.
