New optical memory system could revive CDs and DVDs

techspot.com

Researchers at the University of Chicago and Argonne National Lab have created a new optical memory system that could revive CDs and DVDs. This system uses rare-earth elements to significantly increase data storage density. The new method overcomes the limitations of traditional optical storage by using wavelength multiplexing. This allows multiple data bits to be stored at different light wavelengths, potentially packing more information into the same space. While the initial findings are promising, key questions remain about data retention and capacity. The researchers acknowledge that further development is needed before this technology can be commercialized.
