Titanium oxide crystals can significantly increase disc storage capacity

Posted on Saturday, May 29 2010 @ 17:11:02 CEST by


Japanese researchers have discovered that a new crystal form of titanium oxide could be used to make cheap discs with data storage capacity thousands of times greater than a DVD.
According to Shin-ichi Ohkoshi, chemistry professor at the University of Tokyo, the material transforms from a black-color metal state that conducts electricity into a brown semiconductor when hit by light.

The material can switch back and forth between the metal and semiconductor states at room temperature when exposed to light, creating an effective on-off function for data storage. The material is made from a new crystal form of titanium oxide.
