Toshiba today released a 2.5in, double-platter hard disk drive that it said features the highest density yet of any such component.
The disk uses perpendicular magnetic recording technology to hold 277.1 megabits per square millimeter, or 178.8 gigabits per square inch. This density surpasses the current record, which Toshiba holds at 133 gigabits per square inch. The drive itself is designed to hold 200GB.
Mass production of the disks will begin in August, the company said.
The 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.
Microsoft announced on Friday that it would work with Japanese partners to develop the device using a version of its Windows operating system, designed to take market share from Apple's iPod. The company did not provide a target release date for the product.
