A new type of DVD technology will enable users to store 212,000 times the amount of data of a standard 4.7 GB disc, thanks to the work of Australian researchers.

Scientists from Swinburne University made the breakthrough by using two lasers--one to write data and the other to block the majority of the beam. The approach makes it possible to write data on a scale of nine nanometers, enabling more data to fit on a DVD.

A single DVD will be able to store approximately 50,000 high-definition movies, according to project leader Zongsong Gan. He says more people are choosing online streaming services over DVD, but he believes there will be a demand for a hard copy of data in the future. Gan envisions everyone having accounts for data, such as bank accounts today, and all of their data will be saved in a data bank. "Everyone no longer needs the same things today as phones, iPads, or laptops," he says. "We only need a soft touchscreen, any data processing, while storage is done remotely."
