書き換え型デジタル多用途ディスク用新規保護層材料の開発 Development of a New Protective Layer for Rewritable Digital Versatile Disks
A new protective layer for the rewritable digital versatile disk (DVD) of high transfer rate has been developed. High erasability was achieved using a tantalum oxide (Ta<SUB>2</SUB>O<SUB>5</SUB>)-based material as a protective layer for the four-layer structured optical disks. It was confirmed that the tantalum oxide of high contact angle promoted the nucleus formation in the active layer of Ge<SUB>2</SUB>Sb<SUB>2</SUB>Te<SUB>5</SUB>, leading to enhancement of erasability. This new protective layer proved to be promising in the use for next generation rewritable DVD of blue laser type.
