BLU-RAY DISC MADE FROM DISCARDED CD OR DVD DISCS
摘要:
Briefly, in accordance with one embodiment of the present principles, a Blu-ray disc is described. The Blu-ray disc has a structure including a substrate having one of either a Compact Dics data layer and a DVD data layer along with a Blu-ray data layer. The Blu-ray discs of the present invention advantageously use Compact Discs (or DVDs) that are due to be scrapped or recycled as donor substrates for new Blu-ray discs, thereby saving polycarbonate material and eliminating the need to purchase injection molding equipment to manufacture Blu-ray discs.
