Digital signal processing in read channels
Erich F. Haratsch, Z.A. Keirn · 2006
Digital signal processing (DSP) has been a key technology in read channels, contributing significantly to the dramatic storage capacity and data rate growth of hard disk drives. This tutorial paper provides an overview of magnetic recording trends, and it discusses the DSP algorithms and architectures that have been employed in read channels for equalization, detection and coding. This paper also presents both a read channel and a hard disk drive SoC chip in 0.16 /spl mu/m CMOS process.
