A simple partial erasure model based on the effective reduction of the transition width in a magnetic recording system is presented. This model predicts nonlinear distortion accurately at high recording densities. This paper proposes several detection schemes incorporating this nonlinear model, and compares the performance with receivers designed for a linear channel. Simulations show that the nonlinear equalized maximum likelihood (EML) receiver outperforms other detectors in a nonlinearity-dominant channel.
