ABSTRACT OF THE DISCLOSURE A magnetic detector for the angle, position or speed of rotation of a rotating body or the rectinear position, distance or speed of a rectinearly moving body is used opposite to a magnetic recording medium. The magnetic detector includes a plurality of elongated stripe-shaped magnetoresistive elements juxtaposed on a non-magnetic substrate. Bridge output terminals are provided adjoin- ing to first identical ends of the respective magneto- resistive elements in the longitudinal directions thereof while common terminals are disposed adjoining to second ends of the magnetoresistive elements. Either bridge output or common terminals extend round the outside of the magnetoresistive elements to positions adjacent to the common or bridge output terminals. Thus, the total width of the magnetoresistive elements pattern can be greatly reduced, thereby providing a magnetic detector of high performance in which the influence of fluctu- ations of gap or spacing between the magnetic ditector and the magnetic recording medium used together therewith.
