Toshiba today announced a 1.8-inch drive that offers a storage capacity of 100 gigabytes, the largest capacity yet achieved in this class of HDD. The new drive, MK1011GAH, employs perpendicular magnetic recording (PMR) technology and an improved error correction code to secure the highest areal density of any 1.8-inch HDD in the market, 240.8 megabits per square millimeter (155.3 gigabits per square inch). Toshiba will start mass production of this new best-in-class drive from January 2007.
Alongside capacity improvement, Toshiba has also improved power consumption to 0.003W/GB, as defined in the Ministry of Economy, Trade and Industry's Energy Conservation Law, assuring a more environmentally friendly design. The new drive also complies with the EU's RoHS directive, which came into force in July 2006.
