Abstract: A thermally assisted magnetic head is formed by performing a head forming process, a mounting part forming process and a light source mounting process in that order. In the head forming process, a planned area is secured on a light source placing surface of a slider substrate, then a magnetic head part is formed on a head area other than the planned area and a spacer for securing a mounting space for the laser diode is formed on the planned area. In the mounting part forming process, a light source mounting part is formed by removing the spacer. In the light source mounting process, a laser diode is mounted on the light source mounting part formed by the mounting part forming step.

Abstract: A method for manufacturing a thin film magnetic head with a write element, the write element having a first yoke portion and a second yoke portion connected to each other by a back gap portion, a first pole portion and a second pole portion disposed in the medium-facing surface side of the first yoke portion and the second yoke portion respectively, a gap film disposed between the first pole portion and the second pole portion, and a coil surrounding in a spiral form the back gap portion, and the manufacturing method including the steps of forming the coil above the first yoke portion, forming a part which the first pole portion is composed of so that the part extends to cover the upper surface of the coil, forming the gap film on the first pole portion, forming the second yoke portion, which includes the second pole portion, above the gap film, and trimming the first pole portion so as to have a width fitting the second pole portion.

Abstract: A magnetic head comprises a pole layer, a gap layer, a shield layer, a nonmagnetic layer, and a coil. The shield layer incorporates: a first layer disposed on the gap layer; a second layer disposed on the first layer; a two-layered coupling layer disposed on a region of the pole layer where an opening of the gap layer is formed; and a third layer disposed to couple the second layer to the coupling layer. The first layer defines throat height TH. The nonmagnetic layer is disposed on a side of the first layer. The coil is disposed on the nonmagnetic layer on a side of the second layer.

Abstract: A method and system for providing a magnetic memory are disclosed. The method and system include providing a plurality of magnetic memory cells and at least one programmable current source. Each of the plurality of magnetic memory cells includes a first magnetic element. The programmable current source(s) are for programming a portion of the plurality of magnetic memory cells. Each of the programmable current source(s) includes a controller and a current source coupled to the controller. The controller is for determining a current provided by the current source and includes at least a second magnetic element. The second magnetic element(s) are substantially the same as the first magnetic element. The controller determines the current provided by the current source based on the at least the second magnetic element.

Abstract: In a write element of a thin film magnetic head, a second pole portion has a reduced width in the medium-facing surface side. A first pole portion includes a trimmed portion in such a position that the trimmed portion faces the second pole portion in the medium-facing surface side, and the trimmed portion has a reduced width to fit the second pole portion. The first pole portion includes an extending portion that extends so as to cover one surface of a coil facing the second pole portion. To manufacture the thin film magnetic head, a part which the first pole portion is composed of is formed so that said part extends to cover the upper surface of the coil, and the first pole portion is trimmed so as to have a width fitting the second pole portion.
