Abstract:
A transducer comprising:a magnetoresistive sensor containing plural layers disposed substantially parallel to a plane, said layers terminating at an end extending at a first angle from said plane,an amagnetic layer adjoining said magnetoresistive sensor along a first interface substantially aligned with said plane, said first interface terminating at said end and said amagnetic layer having a second interface extending from said end at a second angle to said plane, said second angle being substantially less than said first angle, wherein said amagnetic layer essentially contains at least one material from the group consisting of polycrystalline DLC, ta-C, cubic-BN, AlB.sub.12, ZrO.sub.2, Nb.sub.2 O.sub.5, Y.sub.2 O.sub.5, HfO.sub.2, MgO, and BaTiO.sub.3, anda metal layer adjoining said end along a junction and adjoining said amagnetic layer along said second interface, whereby said metal layer provides a bias to said sensor without penetrating said amagnetic layer.
