Dois modelos de pulso isolados, o modelo Lorentziano e o modelo Mixture, foram utilizados para investigar o efeito de cabeças-mídia GMR com diferentes parâmetros geométricos e magnéticos no formato do pulso de readback. A correspondência destes dois modelos com um pulso real foi comparada detalhadamente. A dependência do formato do pulso de leitura do cabeçote GMR nos parâmetros cabeçote-mídia e nas distorções não lineares foi discutida neste artigo. Ao aplicar estes modelos para avaliar o desempenho de um sistema de gravação, é necessário levar em conta a diferença entre a superposição linear do pulso isolado e o padrão real de dados de leitura. Foi sugerido linearizar o pulso isolado capturado para utilizar o modelo corretamente como uma ferramenta útil para avaliar o desempenho do sistema.

Abstract: Two isolated pulse models, the Lorentzian-like and the Mixture model, were used to investigate the effect of GMR heads-media with different geometric and magnetic parameters 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. When applying these models to evaluate the performance of a recording system, it is necessary to take into account of the difference between the linear superposition of the isolated pulse and the actual readback data pattern. It was suggested to linearize the captured isolated pulse in order to use the model correctly as a useful tool for evaluating the system performance.
