Abstract :
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-Sb2Te3 films shows high record-read performance for 50GB/φ 120mm capacity and a high data rate of 35Mbps with sufficient feasibility.
