Toshiba announced a new 2.5-inch hard disk drive (HDD) that uses perpendicular magnetic recording technology to achieve the largest 200GB capacity with only two platters, in 9.5mm high HDD section.
The slim MK2035GSS drive has 69.85 x 100 x 9.5 mm, and it contains only two hard-disk platters. It features the highest areal density yet achieved of 277.1 MB/mm2 (178.8 GB per square inch). It boosts data capacity to 1.67 times that of Toshiba’s highest capacity conventional 2.5-inch drive (Toshiba’s current 2.5-inch 120GB HDD, MK1234GSX).
Small form factor HDDs are now used from mobile PCs and to digital audio players. By applying perpendicular magnetic recording technology to 2.5-inch HDD, Toshiba brings much increased data capacity to the industry’s mainstream drive, a move that will also sustain the industry trend to thinner and lighter notebook PCs.
Toshiba will feature the new drive at Computex Taipei 2006, held in Taiwan from June 6 to 10. The mass production is planned to start in August 2006.
