Abstract: A thin-film magnetic head comprises a reproducing element formed on an undercoat film on a head substrate surface, a recording element formed on the upper side of the reproducing element, and a heater formed on the upper or lower side of the reproducing element, the heater generating heat upon energization so as to project at least the reproducing element by thermal expansion toward a recording medium. A shield layer is formed between the reproducing element and the heater by a plurality of layers including at least first and second shield layers. In the first and second shield layers, the second upper shield layer located closer to the heater is formed by a material having a coefficient of thermal expansion smaller than that of the first shield layer located closer to the reproducing element.

Abstract: In a method for manufacturing a perpendicular magnetic recording head, a groove defined by the inner side surfaces of a first nonmagnetic layer and the top surface of a main magnetic pole layer is formed using the difference in etching rates for dry etching between the main magnetic pole layer and the first nonmagnetic layer. An auxiliary magnetic pole layer is formed on the groove with a nonmagnetic material layer disposed therebetween. A projection integrated with the auxiliary magnetic pole layer is formed in a recess of the nonmagnetic material layer on the groove. This projection extends toward the main magnetic pole layer.

Abstract: First and second magnetic layers of a magnetic head face each other. A toroidal coil layer having upper and lower layer coil pieces (ULCP and LLCP) is wound around one of the magnetic layers. The ULCP extend from a first insulating layer by downward steps to a top of a second insulating layer which is widened at ends of the first insulating layer. Side ends of the first insulating layer extend parallel to a height direction. The ULCP are orthogonal to the side ends. Each of the LLCP is formed on a third insulating layer and has a straight region extending in the same direction as the upper layer coil pieces and a curved region curved toward a facing surface or in a height direction on one end in the track width direction. An end of each of the straight and curved region is connected to an ULCP.
