How Perpendicular Recording Works

The majority of hard disk drives found on the market today use a recording technology called longitudinal, where bits are stored side by side on the magnetic surface. This recording technique has been used since the first hard disk drives. A new recording technology, called perpendicular, is being used on newer hard disk drives, allowing a higher recording density. In this tutorial we will explain you everything you need to know about perpendicular recording and how data is stored on the hard disk drive magnetic surface.
