A magnetic detector for detecting the angle, position 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 adjoining to first identical ends of the respective magnetoresistive 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 fluctuations of gap or spacing between the magnetic detector and the magnetic recording medium used together therewith. |

DETAILED DESCRIPTION An object of the present invention is to provide a magnetic detector which is scarcely affected by the spacing and has a high sensitivity of detection.
In the present invention, an elongated stripe-shaped magnetoresistive element is used instead of the combination of two magnetoresistive elements, and a plurality of such stripe-shaped magnetoresistive elements are arranged to form a bridge circuit.
According to the present invention, there is provided a magnetic detector used in an arrangement close to and opposite to a magnetic recording medium with a relative movement provided between the magnetic detector and the magnetic recording medium, the magnetic detector comprising a plurality of elongated stripe-shaped magnetoresistive elements formed in juxtapositional relation with one another on a non-magnetic substrate, bridge output terminals provided adjoining to respective one-side ends of said magnetoresistive elements in the longitudinal directions thereof, and a common terminal arrangement provided adjoining to the other-side ends of said magnetoresistive elements in the longitudinal directions thereof, said common terminal arrangement extending round the outside of said magnetoresistive elements to a position adjacent to said bridge output terminals provided at said one-side ends of said magnetoresistive elements.
According to the present invention, there is also provided a magnetic detector used in an arrangement close to and opposite to a magnetic recording medium with a relative movement provided between the magnetic detector and the magnetic recording medium, the magnetic detector comprising a plurality of elongated stripe-shaped magnetoresistive elements formed in juxtapositional relation with one another on a non-magnetic substrate, a common terminal arrangement provided adjoining to one-side ends of said magnetoresistive elements in the longitudinal directions thereof, and bridge output terminals provided adjoining to the respective other-side ends of said magnetoresistive elements in the longitudinal directions thereof, said bridge output terminals extending round the outside of said magnetoresistive elements to positions adjacent to said common terminal arrangement provided at said one-side ends of said magnetoresistive elements
