Abstract: A processing jig of the invention is provided for deforming an object to be processed that is long in one direction into a complicated shape and processing the object with accuracy. The jig comprises: a main body to be fixed to a processing apparatus; a retainer that is long in one direction for retaining a bar as the object long in one direction; four couplers for coupling the retainer to the main body; five load application sections, coupled to the retainer, to which a load is applied for deforming the retainer; and arms for coupling the load application sections to the retainer.

Abstract: A method of manufacturing a magnetic head apparatus provided with a slider having an ABS includes a step of aging a bar with a plurality of sliders, a step of lapping a surface or the bar, the surface including the ABS to be formed, the lapping step including a final lapping process for finally lapping the surface of the bar, a step of forming rails of the respective sliders of the bar after the final lapping process, the forming step including a photolithographic etching process to form the rails, and a step of cutting the bar to separate into the individual sliders. The aging step is carried out before the final lapping process or with the final lapping process.

Abstract: A processing jig is provided for deforming an object to be processed that is long in one direction into a complicated shape and processing the object with accuracy. The jig comprises: a main body to be fixed to the processing apparatus; a retainer that is long in one direction for retaining a bar as the object long in one direction; four couplers for coupling the retainer and the main body to each other; three load application sections, coupled to the retainer, to which a load is applied for deforming the retainer; and arms for coupling the load application sections to the retainer. The retainer takes a shape of a narrow and long beam that is bent with an application of external force. The two load application sections on both ends each have three degrees of freedom in two directions orthogonal to each other and a direction of rotation, for example. The load application section in the middle has one degree of freedom in the vertical direction only.
