Western Digital (WD) may have lost a bid to buy Toshiba's flash memory technology, but is still hard at work on its bread-and-butter hard drives. The company has unveiled a breakthrough called microwave-assisted magnetic recording (MAMR) that will allow ever-higher disk capacities, up to 40TB by the year 2025. "Commercialization of MAMR technology will pave the way to higher recording densities and lower cost per terabyte hard disk drives," said VP of research John Rydning in a statement.
