The Hyper CD-ROM is an optical data storage device similar to the CD-ROM with a multilayer 3D structure, invented by Romanian scientist Dr. Eugen Pavel. == Characteristics == The disc has a height of 1.2 mm and a diameter of 120 mm and can be produced with existing technology. The storage capacity of one such disk is 1,000,000 GB (1 PB), as storage occurs on 2 000 different levels layered inside the glass body of the disk. * Capacity: 1 PB (with possibility of extension up to 100 EB) * Medium transfer rate: 300 Mbit/s (may be more) * Hard drive dimensions: 80 x 150 x 300 mm * Disk dimensions: 1.2 mm ø 120 mm * Temperature resistance: up to 550°C * High reliability * Maximum usage period: 5,000 years In November 1999, the disk was presented at EUREKA "48th World exhibition of Innovation and New Technology" in Brussels. The technology has gained recognition in 21 countries including the U.S., the EU, Canada, Japan and Israel. There has not been any large-scale production of the Hyper CD-ROM, although several firms like IBM, Compaq, Philips and other Hollywood businesses have taken an interest in this form of data storage. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hyper CD-ROM」の詳細全文を読む スポンサード リンク
