ABSTRACT:
An apparatus for detecting the position of a moving member comprising a moving member having a magnetic substance with magnetical signals recorded thereon, and a stationary magnetic sensor confronting the moving member and having a plurality of magnetoresistive elements, wherein the magnetoresistive elements are disposed in the magnetic sensor such that the elements have a phase difference of .pi./m in electrical angle, where m is an even number larger than or equal to four, for obtaining the positional signal of the moving member.
