Laser-Writing Method Supports Long-term 5D Optical Data Storage
SOUTHAMPTON, England, Nov. 1, 2021 — University of Southampton researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. The resulting tiny structures can be used for long-term five-dimensional (5D) optical data storage that is more than 10,000× denser than Blu-ray optical disc storage technology. “Individuals and organizations are generating ever-larger data sets, creating the desperate need for more efficient forms of data storage with a
Laser breakthrough could soon enable 1-TB optical storage
SENDAI, Japan – Numerous research labs are looking for ways to increase the amount of information one can store on a CD-ROM or related optical disc, but the equipment needed to push past the boundaries of Blu-ray technology is exceedingly large and expensive....
Dual-Layer Coatings Target Next-Generation Optical Discs
Dec 1, 2004 — With the emergence of the Blu-ray video recording format, end users can record, rewrite and play back at least two hours of digital HDTV or more than 13 hours of standard video on a single optical disc. Currently, however, Blu-ray systems are found...
