Modeling of Readback Pulse Shape of GMR Head

摘要

Two isolate pulse models, the Lorentzian - like and the Mixture model, were used to investigate the effect of GMR hads - media with different grometric and magnetic pa - Rameters on the readback pulse shape. The matching of these Two models with an actual pulse was compared in detail. The Dependence of the readback pulse shape of GMR head on the Head - media parameters and non - linear distortions was discussed In this paper.
