Detection of media defects in perpendicular magnetic recording channels
Weijun Tan, J.R. Cruz · IEEE Transactions on Magnetics · 2005
Two new algorithms for detection of media defects in perpendicular magnetic recording channels are proposed. These algorithms are based on amplitude thresholding of the channel reliability information. The performance of these algorithms is evaluated for low-density parity-check coded channels using generalized partial response targets with different dc-components.
