Abstract:
1. A method of manufacturing a load beam that is installed in a hard disk drive to read and write a hard disk, the load beam having a body, a slope extending from a front end of the body and bent along a bend line in a direction opposite to the hard disk, a guided portion protruding from the slope and to be guided on a guide of the hard disk drive, and a box-bent portion extending along each side edge of the body and the slope and passing through an end of the bend line, the method comprising: preparing a load beam material having sections to be processed into the body, slope, guided portion, and box-bent portions of the load beam; forming a deformation control zone on the section to be processed into the box-bent portion of the load beam material corresponding to the section to be processed into the bend line so as to prevent the box-bent portion from deforming and protruding when the box-bent portion is formed; and processing the load beam material provided with the deformation control zones into the load beam having the body, slope, guided portion, and box-bent portions.
