ABSTRACT:
A magnetic sensor comprises a read head, a position identification scale and a motion identification scale. The read head is provided with a position sensing unit opposite the position identification scale, and a motion sensing unit opposite the motion identification scale. The read head is further provided with a signal processing unit that is connected with the position sensing unit and the motion sensing unit. By such arrangements, the sensing accuracy can be improved, and the material cost can be relatively reduced.
