Perpendicular Recording has been promoted as the technology to carry us through the superparamagnetism limit. With low demag fields that improve with increasing density, and the capability to increase coercivity and still be able to write, this technology promises to be the panacea. But why have we not yet seen products; and when will we? Why do companies continue to bet on this technology? How are we going to overcome the obstacles in producing this technology? This class is ideal for those that want to understand the true advantages and the challenges of Perpendicular Recording Technology.
