Four-Reader Array Detection for Two-Dimensional Magnetic Recording

Two-dimensional magnetic recording is a promising technology to achieve magnetic recording areal density of 10 Tb/in
²
. But it suffers severe two-dimensional intersymbol interference (2-D ISI). We propose a novel detection architecture which uses a four-reader array to retrieve the recording data. Simulation results show that the proposed approach outperforms both the conventional single reader detection and three-reader array detection.
