The Toshiba MK2035GSS drive uses perpendicular magnetic recording technology, increasing data capacity to 67% more than a conventional 2.5-inch Toshiba drive.
The new product stores data in magnetically charged bits, as in conventional hard disc drives. But in perpendicular recording, the bits stand upright rather than lying flat on the disc surface, saving space and allowing a greater storage capacity.
The MK2035GSS drive contains only two platters – the physical discs inside the drive – keeping the height to 9.5mm.
Increasing use of laptop PCs, mobile devices and digital audio players is boosting demand for demand for smaller, thinner hard drives with high capacities.
Toshiba will show the new drive at the Computex Taipei 2006 exhibition in Taiwan this week. The new drive will go into production in August 2006.
