| Abstract: | An AMR magnetic head with eliminating harmonics and sinusoidal wave output was designed. This magnetic head is made from AMR thin film material by micro-fabrication technique. The harmonics analysis and testing of output waveforms of magnetic head were completed. This magnetic head has excellent sinusoidal wave transfer characteristic and sensitivity of magnetic fields and Signal-to-Noise. The magnetic heads are expected to be widely used in the systems of high accuracy displacement measure by magnetic railings ruler and angle measure by magnetic rotary encoder. |
