Perpendicular and Longitudinal Recording : A Signal-Processing and Coding Perspective

  title={Perpendicular and Longitudinal Recording : A Signal-Processing and Coding Perspective},
  author={Roy D. Cideciyan and Evangelos Eleftheriou and Thomas Mittelholzer},
Equalization and noise prediction followed by sequence detection and postprocessing are studied for double-layer perpendicular recording channels that are corrupted by electronics and transition noise. The performance of various outer coding schemes, such as conventional Reed–Solomon codes with 8and 10-bit symbols and low-density parity check codes, is evaluated, and a signal-processing and coding perspective is presented for both longitudinal and perpendicular recording channels. Finally, the… CONTINUE READING
