Abstract

線形信号解析(LSA)は線形動作しているGMRヘッドの再生出力およびパルス幅を推定する方法である。LSAの確度を向上させるために、媒体磁化分布と磁区制御磁石による不均一バイアスの効果を考慮した精度の高いLSAを開発した。この新しいLSAを使って再生波形の計算を行ったところ、ピーク出力とPW50の計算値は実験値と誤差10%以内であり、良好な一致が得られた。

Linear signal analysis (LSA) is the conventional method of estimating the playback voltage and pulse width in linearly operating shielded GMR heads.To improve the accuracy of LSA, we developed a new, highly precise LSA which includes the effect of the distribution of magnetization in the medium and inhomogeneous biasing by domain control magnets. Utilizing this new LSA to calculate the playback waveforms, the calculated peak voltage and pulse width were compared with the experimental values and good agreement within 10% was obtained.
