Abstract
A planar magnetic head including two pole pieces separated by a head gap with a longitudinal multilayer magnetoresistance component MR comprising extending longitudinally beneath the pole pieces and the head gap and separated from the pole pieces by an insulating layer. The MR component is arranged in contact with a pair of spaced apart electrical conductors for connecting said MR component in circuit with a source of electrical power to cause current to flow through said MR component in its lengthwise direction.
