Abstract: In a thin-film magnetic head, a lower magnetic pole layer and a planarizing magnetic layer in continuity with the lower magnetic layer are arranged. Since a coil formation surface is positioned lower than the top surface of the lower magnetic pole layer and the planarizing magnetic layer, the front end of an upper magnetic core layer is formed to be a predetermined track width with a high accuracy. A thin-film magnetic head having good information writing characteristics and a method for manufacturing the thin-film magnetic head are thus provided.

Abstract: A main magnetic pole layer is formed on an insulating layer flattened into a high-flatness surface, and a yoke layer having a large film thickness is formed under the main magnetic pole layer independently of the main magnetic pole. The main magnetic pole layer has a front end surface formed in a shape with a width size gradually increasing in a direction of track width as the front end surface departs farther away from an auxiliary magnetic pole layer. A perpendicular magnetic recording head can be provided which can suppress the occurrence of fringing in a recording pattern, and can form the main magnetic pole layer with high pattern accuracy, and can satisfactorily introduce a recording magnetic field to a fore end of the main magnetic pole layer.

Abstract: A TIG welding apparatus comprises; a twin electrode type welding torch 1 having a first and a second welding electrode 1a, 1b arranged approximately parallel and either side of an insulation plate of a predetermined thickness, and a main unit 2 which supplies to the first welding electrode 1a a first welding current varied at a first period F, and to the second welding electrode 1b a second welding current varied at the first period F and at an opposite phase to the variation of the first welding current. The main unit 2 superimposes a variation of a second period fm being shorter than the first period F, onto the first and second welding currents. As a result, the arc current is increased without increasing the welding current.
