perpendicular magnetic recording (PMR), Toshiba’s new MK1011GAH uses two platters to achieve the size but does it in 10 percent smaller space than previous 1.8-inch drives. Full specs can be seen after the jump, but basically the “why should I care?” on this one is that breakthroughs like this mean that your next iPod portable media player could be sporting more than 100GB of storage while being smaller and weighing less.
