Analisis isyarat linear (LSA) ialah kaedah konvensional untuk menganggar voltan main balik dan lebar nadi dalam kepala GMR terlindung yang beroperasi secara linear. Untuk meningkatkan ketepatan LSA, LSA baharu yang sangat tepat yang merangkumi kesan pengagihan magnetisasi dalam pincang sederhana dan tidak homogen oleh magnet kawalan domain, telah dibangunkan. Menggunakan LSA baharu ini untuk mengira bentuk gelombang main balik, voltan puncak yang dikira dan lebar nadi dibandingkan dengan nilai eksperimen dan persetujuan dalam 10% diperolehi. Hasil daripada anggaran menggunakan LSA baharu, adalah dianggap bahawa penggunaan kepala injap berputar jenis menegak akan memungkinkan untuk mencapai ketumpatan kawasan rakaman sebanyak 40 Gb/in.2.

Abstract: 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, a new, highly precise LSA which includes the effect of the magnetization distribution in the medium and inhomogeneous biasing by domain control magnets, was developed. Utilizing this new LSA to calculate the playback waveforms, the calculated peak voltage and pulse width were compared with the experimental values and agreement within 10% was obtained. As the result of estimation using the new LSA, it is considered that the use of a vertical-type spin-valve head will make it possible to achieve a recording areal density of 40 Gb/in2.
