Seagate Technology has announced it has begun shipping the Momentus 5400.3 (PDF), what it claims is industry's first 2.5-inch notebook disk drive with perpendicular recording technology. Loosely described, perpendicular storage increases the data density on a disk drive by storing individual bits in layers on top of each other, rather than side-by-side. Although researchers have speculated about as many as 10 distinct layers of… Read More

To achieve this, Hitachi has demonstrated the industry's highest data density at 230 gigabits per square inch (Gb/in2) on perpendicular recording. Hitachi believes 230 Gb/in2, which represents a doubling of today's highest longitudinal recording densities, will be implemented in commercial hard drive products in 2007. When fully realized over the next 5-7 years, perpendicular recording could enable a 10-fold increase in data… Read More
