[0061] The head suspension manufactured according to the manufacturing method of the first embodiment of the present invention will be described below with reference to FIGS. 1 to 3, wherein FIG. 1 shows the side of the head suspension opposite to the disk according to the first embodiment of the present invention. 2 is a top view of the disk side of the head suspension in FIG. 1, FIG. 3A is an enlarged perspective view partially showing the head suspension in FIG. 1, and FIG. 3B is a cross-sectional view taken along the line III-III in FIG. 3C is a cross-sectional view showing a modification of the first embodiment, and the part shown in FIG. 3C corresponds to the part shown in FIG. 3B. In this specification, a "disk" is a storage medium installed in a hard disk drive and a magnetic head supported by a head suspension to read data from and write data to it. The side facing away from the disk is the side where the head suspension faces away from the disk. On the other hand, th...

[0123] The second embodiment of the present invention will be described with reference to FIGS. 16 to 18. First, the structure of the head suspension will be explained.

[0124] Fig. 16 is a plan view showing a head suspension according to a second embodiment of the present invention. The structure of the second embodiment is basically the same as that of the first embodiment, and therefore, the same or corresponding parts are indicated by the same reference sign or the same reference sign plus "D".

[0125] According to the second embodiment, the head suspension 1D has the load beam 3, the base plate 5, and the flexure 7D. The flexure 7D has, for example, an elastic thin stainless steel rolled plate (SST) having elasticity or hinge capability. On this thin plate 7Da, a read / write wire pattern 83 including a conductor and an insulating layer is formed.

[0126] The elastic member 13D is formed integrally with the thin plate 7Da of the flexure 7D. The elastic member 13D includes b...

Abstract

A method of manufacturing a head suspension includes a rigid part chain product manufacturing step forming a rigid part chain product where the rigid parts are provided continuously, including a rigid part framework forming step forming a plate-like framework for formation of the rigid part including formation margins for formation of the rails and forming a deformable part along a longitudinal curve of each formation margin and a rail forming step forming the rails by bending the formation margins to rise, a resilient member chain product manufacturing step forming a resilient member chain product where the resilient members are provided continuously, a flexure manufacturing step forming the flexures, a base manufacturing step forming the bases, a stacking and coupling step stacking and coupling the rigid part chain product, the resilient member chain product, the bases, and the flexures, to form a stacked set, and a cutting step cutting and separating respective head suspensions from the stacked set.

Description

Technical field [0001] The present invention relates to a method of manufacturing a head suspension of a hard disk drive (HDD) integrated in an information or data processing device such as a personal computer. Background technique [0002] The head suspension of the hard disk drive includes a load beam, a magnetic head supported by the load beam, and a slider connected to the magnetic head. The head suspension has an impact characteristic that determines that the slider is lifted from the surface of the hard disk when an impact is applied. The impact characteristics of the head suspension depend on the weight of the load beam. [0003] For example, the first head suspension has a load beam with a thickness (t) of 51 μm and a length (1L) of 7 mm, and the gram load applied to the head by the load beam is 2.5 gf, and the second head suspension has a thickness (t) It is a load beam of 30 μm and a length (1L) of 5.5 mm, and the gram load is 2.5 gf. If an impact lasting 1 millisecond...
