Summary :

As the track becomes narrower, the effects of track edge become more significant. These effects, such as the amplitude reduction, variations in the shape of the isolated pulse, the partial erasure and the amplitude asymmetry, are dependent on head/disk combination and the off-track position. These relationships are discussed in detail in this paper. More importantly, an off-track model is proposed to study the off-track BER performance for the head with narrow track width. The BER performances of EPRML channel for different off-track cases and different head/media combinations are studied based on this model. Simulation results have proved that this model is a useful tool for simulation of system performance.
