Abstract:
A magnetoresistive head, comprising:a lower shield layer formed on a substrate and made of soft magnetic material; a lower gap layer formed on said lower shield layer and made of insulating material; a pair of magnet films formed on said lower gap layer at a predetermined distance therebetween, said pair of magnet films defining a recess on said lower gap layer, the recess having generally an inverted trapezoid shape in cross section; a magnetoresistive film covering a bottom and side wall of the recess and partial upper surfaces of said pair of magnet films; and a pair of electrically conductive films, one of which is formed on one magnet film of said pair of magnet films and the other is formed on the other magnet film of said pair of magnet films, and being in contact with said magnetoresistive film only at a position outside of the recess.
