Tóm tắt

The requirements for dual layer optical disc from the view point of optical property were reviewed and practical approaches were demonstrated. It was experimentally confirmed that our new rewritable blue dual-layer optical disk with (Ge,Sn)Te-Sb/sub 2/Te/sub 3/ films shows high record-read performance for 50GB//spl phi/ 120mm capacity and a high data rate of 35Mbps with sufficient feasibility.
