Abstract: Embodiments in accordance with the present invention provide a thin film magnetic head for preventing a short-circuit failure during formation of a track portion or a stripe-height portion and improving a yield. In one embodiment, a stripe-height direction is first formed, and then a track-width direction is formed. A third insulating film having a smoothly shaped wall surface is formed on a first insulating film during stripe-height formation. During formation of the third insulating film, an optimized lift-off pattern is used to smooth an edge shape.

Abstract: Embodiments of the present invention provide a magnetic head having a read head of stable reading operation and with less magnetic fluctuation noise. According to one embodiment, a free layer has a structure comprising two ferromagnetic layers (a first free layer and a second free layer) that are coupled anti-ferromagnetically by way of a non-magnetic intermediate layer, in which the magnetization amount of the first free layer is set to larger than the magnetization amount of the second free layer. Further, the magnetic domains in the first free layer and the second free layer are stabilized simultaneously by increasing the distance between the second free layer and the magnetic domain control film to be more than the distance between the first free layer and the magnetic domain control film, thereby adjusting the magnetization amount of the magnetic domain control film.
