CES 2004: In a feat of miniturization Toshiba has today revealed it is working on the worlds first sub 1 inch Hard Disk Drive. The new 0.85 inch HDD will have a capacity between 2 and 4 GB. This new device is clearly aimed at the portable music / multimedia players, PDA's and pocket notebook PC's. However it's not a far stretch to imagine these HDD's in use in digital cameras and 'cross over' products which also shoot digital video.
