Abstract:Optimizing the materials properties and structure parameters of giant magneto-resistance head are of key importance to application. Based on the physics computation model in this work, we firstly calculated the signal field and magnetization distribution in free layer using transmittance line model and micro-magnetic theory, and then we discussed the effect of size and magnetic parameters on the magnetic flux and signal field; finally, we put the head on a suitable front-end electric circuit which acts as a variation magneto-resistance, and analyzed the output voltage, harmonic signal and line range. The simulated results show that output signal has good linear characteristic with respect to the medium recording signal in a wide range of gap length （g1＋g2≤0.7）. The optimal value of sensing current should be selected between 10 mA and 50 mA.
