Japanese to Make DVD 1000 Times Larger Than Blu-Ray disc

As is reported by insider, Japanese researchers are developing a disc that could hold over 25,000GB of data per disk thanks to a new technique for storage.

Researchers in Japan have found a new material for optical storage that is easy to manufacture, safe to use, and it could increase disk capacity by over 1,000 times over single-layer Blu-ray discs. (Blaze 3GP Video  Converter)

A new synthetic material would coat the discs in a metal film. In darkness, the metal remains black and can conduct electricity. When struck by light, the material transforms into a brown semi-conductor. The light itself would act as an on-off switch.(Photo Editor)

The material is a new crystalline form of titanium oxide that Shin-ichi Ohkoshi, the lead researcher, described in an interview as a being ?promising as a material for a next-generation optical storage device.?

Different colors reflect light differently, and each difference can be used to store new sets of information.  The researchers have created the material in particles that are between 5 and 20 nanometers, or a five-billionth to 20-billionth of a meter in diameter. Using the smallest particle, the disks could hold over 1,000 times as much as a Blu-ray disc by reflecting light in different ways.

?You don?t have to worry about procuring rare metals. Titanium oxide is cheap and safe, already being used in many products ranging from face powder to white paint,? Ohkoshi said.

Assuming that the proper reading and writing equipment is also developed, the new synthetic metal could be a giant leap in optical storage. Surprisingly for such a leap in technology, neither cost nor availability would be an issue.(Audio DVD Maker)

No word on when these new discs might reach the public, but Ohkoshi says that they will soon begin talking to private-sector companies about commercializing the technology.
