A new optical recording method could pave the way for data discs with 300 times the storage capacity of standard DVDs, Nature journal reports.
The researchers say this could see a whopping 1.6 terabytes of information fit on a DVD-sized disc. They describe their method as "five-dimensional" optical recording and say it could be commercialised. The technique employs nanometre-scale particles of gold as a recording medium.
Researchers at Swinburne University of Technology in Australia have exploited the particular properties of these gold "nano-rods" by manipulating the light pointed at them. The team members described what they did as adding two "dimensions" to the three spatial dimensions that discs already have...
