摘要： A magneto-resistance effect type thin film magnetic head which does not produce significant Barkhausen noises and has stabilized characteristics even where the track width is smaller than, for example, 10 .mu.m. The magnetic head comprises a base member, a lower layer thin film magnetic core and an upper layer thin film magnetic core layered on the base member in such a manner that a magnetic gap is formed between front ends thereof, the gap being open to an opposing face of the magnetic head which is in contact with or opposed to a magnetic record medium, and a magneto-resistance effect magnetic sensing section disposed in the magnetic gap between the lower and upper layer thin film magnetic cores. The front end of the lower layer thin film magnetic core which defines the magnetic gap has a width selected to be smaller than the width of the front end of the upper layer thin film magnetic core which defines the magnetic gap so as to define a track width of the magnetic gap.

摘要： A magneto-resistive effect type magnetic head employing a spin valve film in which the direction of magnetization of a free layer is constant even in the absence of an external magnetic field to assure magnetic stability. The magneto-resistive effect type magnetic head includes a magneto-resistive effect film of a planar substantially rectangular configuration, having its longitudinal direction substantially perpendicular to a magnetic recording medium sliding surface, a first electrode connected to a longitudinal end of the magneto-resistive effect film, a second electrode connected to the other longitudinal end of the magneto-resistive effect film and hard magnetic films arranged on both ends along the width of the magneto-resistive effect film. The magneto-resistive effect film is made up of at least a first ferromagnetic layer, a non-magnetic layer, a second ferromagnetic layer and an anti-ferromagnetic layer, layered together. The hard magnetic films has an electrical resistance larger than that of the magneto-resistive effect film.

摘要： A magneto-resistance effect type magnetic head incorporates a grounded conductive layer, a second thin film magnetic core and an MR sensing part, the conductive layer being located near the thin film magnetic core, the layer and the core being electrically connected. The conductive layer is further connected electrically to an electrode of the MR sensing part, the electrode facing an air bearing surface. This setup protects the MR sensing part from static electricity destruction, thus providing a magneto-resistance effect type magnetic head of high reliability.
