Scientists Pack 500TB of Data into CD-Sized Glass Disc

Postby Ian on Wed Nov 03, 2021 12:44 pm

I feel like we hear about these new optical storage technologies every couple of years and nothing ever happens with them.

Researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. These tiny structures can be used for long-term five-dimensional (5D) optical data storage that is more than 10,000 times denser than Blue-Ray optical disc storage technology.

“Individuals and organizations are generating ever-larger datasets, creating the desperate need for more efficient forms of data storage with a high capacity, low energy consumption and long lifetime,” said doctoral researcher Yuhao Lei from the University of Southampton in the UK. “While cloud-based systems are designed more for temporary data, we believe that 5D data storage in glass could be useful for longer-term data storage for national archives, museums, libraries or private organizations.”

It can write a whopping 230 kilobytes of data per second. In comparison, a CD written at 1x is 153 kilobytes per second
