Toshiba has released a 200GB 2.5in, double-platter hard disk drive (HDD) that it says features the highest density yet of any such component.
The disk uses perpendicular magnetic recording technology to hold 277.1 megabits per square millimetre, or 178.8 gigabits per square inch. This density surpasses the current record, which Toshiba also holds, at 133 gigabits per square inch.
Mass production of the disks will begin in August, the company said.
The new technology may play a role in Toshiba's planned digital audio player to be developed in conjunction with Microsoft and Japan's NTT DoCoMo for the Japanese market.
