Other tech: Holographic-memory discs may put DVDs to shame
The discs, developed by InPhase Technologies, based in Colorado, US, hold 300 gigabytes of data and can be used to read and write data 10 times faster than a normal DVD. The company, along with Japanese partner Hitachi Maxell announced earlier in November that they would start selling the discs and compatible drives from the end of 2006. InPhase says the technique could theoretically be used to store up to 1.6 terabytes of data on the same size of disc and to read data at 120 megabits per second. This is 340 times the capacity of an ordinary DVD and 20 times the data rate.
