MAGNETIC HEAD

PURPOSE:To obtain an excellent offtrack characteristic and shielding characteristic even with the narrow-track MR head by disposing electrode patterns in such a manner as to decrease the magnetic fluxes crossing the electrode patterns. CONSTITUTION:The MR element 1 is inserted between two shielding patterns 2 and 3 and is thus formed. The electrode patterns 4, 5 are formed at both ends of the MR element 1 and are so formed as to be nearly perpendicular to the surface of a medium 7. Since the magnetic fluxes from adjacent tracks do not cross each other, the deterioration in the offtrack by the induced electromotive force is prevented. The electrode patterns 4, 5 are so disposed as to reduce the area of the loop formed of the electrode patterns 4, 5 drawn out of both ends of a magnetosensitive part and the magnetosensitive part, by which the quantity of the magnetic flux crossing this loop is decreased and the induced electromotive force is decreased. The excellent shielding characteristic and offtrack characteristic are obtd. even with the track MR head in this way.
