DVD disk now can be found easily in everywhere. Usually, DVD disk comes in 4.5 gigabytes and 8.5 gigabytes capacities. However, in five years later we will see a revolution in DVD disk. Min Gu, an Australian academic and professor of Optoelectronics at Swinburne University of Technology claims that a single DVD disk named Ultra-DVD that able to store 10,000 times than the current DVD will be discovered soon. This particular disk will support the three-dimensional TV, and ultra high definition image.

The Ultra-DVD has the size and thickness as the conventional DVD disk. The main difference is the disk using nano technology in order to be able to store large amounts of file. Scientists believe such disk can be sold in five years and will be a revolution in storing film, music and data.

Professor Min Gu, who led this research in Melbourne Australia said the disk can contain 200,000 movies. "Materials with nano structure can be paired to the disk to increase the data capacity without the need to increase the size," he said.

Nowadays, a single DVD disk has an ability to store 4.5 - 8.5 gigabytes data for a sufficient length movie, with its additional features, and the soundtrack. Fortunately, DVD disk technology has start been shifted by a Blu-ray disk, which has a 50GB capacity. Five years from now, according to Professor Min Gu, it will be shifted to Ultra-DVD which has a 10 terabyte or 10,000 GB capacity.
