Equalizer Design for Bit-Patterned Media Recording System Based on ISI and ITI Estimations by Cross Correlation Functions

Abstract:

Due to ultra-high density, a bit-patterned media recording (BPMR) system experiences two-dimensional (2D) interference--inter-symbol interference (ISI) and inter-track interference (ITI)--which degrades the overall performance of a recording systems. Therefore, we propose a novel single-track equalization and a single track detection that can perform these duties almost equally well. Our novel equalizer design uses ISI and ITI estimation schemes with the help of cross-correlation functions. The simulation result shows that our proposed method is able to achieve a significant performance gain over the one-dimensional (1D) equalization method and the conventional joint-track equalization, especially at higher recording density.
