Lucent and Imation Corp. today announced a joint agreement to collaborate on developing Bell Labs holographic data storage technology for the enterprise storage market.
Recent research advances at Bell Labs, the research and development arm of Lucent, in both disk drive and storage materials technologies indicate that the commercialization of holographic storage is possible. Imation, a leading provider of data storage media, will work jointly with Bell Labs to develop holographic disks.
Holographic storage provides dramatic advances in both data storage density and transfer rates required by the latest Internet applications and data warehousing.
Unlike other storage methods, which record only on the surface of a disk, holographic digital data storage allows recording through the entire thickness of the material, which allows for a huge increase in storage density. In addition, much higher transfer rates are achievable because the data is stored and recalled in "page format," which can be accessed one million bits at a time.
Based on the experimental advances, first generation drives would have the potential to store 125 gigabytes of user data on a removable 5.25-inch disk. This single disk capacity would be equivalent to that of 27 current 4.7 gigabyte DVD (digital versatile disk) disks. The transfer rates would be around 25 times faster than that of DVD.
"With this capacity, the information in a typical large university library could be stored on about 10 holographic disks," said Alastair Glass, director of Bell Labs Photonics Research Lab. "Future generations of devices are expected to store around a terabyte on a single disk with about 150 times the transfer rates of current DVDs."
