ABSTRACT:
The present invention provides a device for supplying an initialization pulse current to at least laminations of a pinned ferromagnetic layer, a non-magnetic metal layer and a free ferromagnetic layer in a magnetoresistive transducer in an initialization pulse current direction which is perpendicular to a predetermined magnetization direction of the pinned ferromagnetic layer and also parallel to an interface between the pinned ferromagnetic layer and the non-magnetic metal layer, wherein the device is electrically connected to opposite ends of the laminations spaced from each other in the initialization current direction for applying a pulse voltage between the opposite ends so as to flow the initialization pulse current in the initialization pulse current direction through the laminations.
