Scientists have reportedly found a way to create a DVD-sized disc that can hold 1,000 terabytes of data – enough to store 40,000 HD movies.
It’s all to do with using lasers in a way akin to a fine tipped pen rather than a felt-tip pen – the old way – to write information to the disc, apparently.
Two lasers have been used to massively increase the storage capacity of a DVD from 4.7 gigabytes. One beam partially blocks the light of the other, allowing all but a point of light just 9 nanometres (seriously small) in width to write information to the disc.
The breakthrough by a team at Swinburne University in Australia could spark a revival for the DVD, which has been challenged by the rise of the Blu-ray format and cloud storage.
Researchers from the university it seems are looking at using the technology to revolutionise data storage centres, which can be huge and use a lot of energy.
Tech news website Pocket-lint quoted team leader Dr Zongsong Gan as saying: “In my mind, I have an vision for our society in the future where everyone will have a databank account just like we all have a bank account today.
“We’ll save all of our data in the data bank. Everyone no longer needs the same things today as phones, iPads, or laptops. We only need a soft touch screen, any data processing, while storage is done remotely.”
