photoxelsThe title reminds me of a tune, but Japanese researchers at the University of Tokyo have found a material that could be used to make a low-price super disc with incredible data storage capacity that we might soon see in future memory cards.
A Blu-ray disc can currently hold 5x more data than a conventional DVD. The new “super disc” can potentially hold more than 1,000 times as much information as a Blu-ray disc.
The material, a new crystal form of titanium oxide, 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 clincher about Titanium oxide is that it is abundant, cheap and safe. It is already being used in many products ranging from face powder to white paint.
