Abstract

A new type of magnetoresistive readout transducer is called MR head for short. In order to obtain rational structure parameters of MR head easily ,the authors have been studying the characteristics of the enlarged model ,which is ten thousand times the size of MR head. The magnetoresistance ΔR of the enlarged head model is very weak. To measure the weak magnetoresistance ΔR ,we have designed an effective measuring system. By means of the test ,a set of reasonable structure parameters has been established.
