Abstract

In this 1D model of Magneto-Optical read channel, the isolated step response is modeled to be a Q function, and an equalizer parameter designing method based on the least square error criterion is given, which is suitable for both linear equalizers and feedback equalizers. The detection method can adopt the threshold detection and Viterbi detection. Although the model is linear, it is easy to simulate the non-linear characteristics like bloom or jitter in Magneto-Optical recording.
