Storing data on conventional DVDs and Blu-Ray disk involves a single laser that burns a mark into the disk’s surfacing, changing its chemistry. The mark represents a 1 or 0, which is the basic binary language of all computer data. But because the marks can’t be smaller than a half the wavelength of the laser beam, there is a limit, to how many marks can be burned into the surface of a disk.

The Swinburne team, led by optoelectronics professor Min Gu, did something different. They used two lasers instead of one.

Too bad none of the "big players" appears to be interested in developing a new optical disc format, so this will probably never become a product...
