The requirement to recording density is always increasing with the rapid development of information technology. MR magnetic head was developed under the situation. The main problem met in the application of MR read head is the Barkhausen noise due to the magnetic domain activities in sensor element. There are reports indicated that magnetic domain will tend to single domain structure when the ratio of length and height of rectangle sensor is over 20 and the problem of Barkhausen noise can be resolved. The element which length, width and height is 300 micrometers , 3 approximately 6 micrometers and 40 nm respectively with the ratio of length and height over 50 is studied by bitter powder method. We found that multi-domain activities exist in sensor resulting from the irregular shape of lead line.
