Embodiment 1

[0034] Refer below figure 1 , figure 2 as well as Figure 8 , Figure 9 The first embodiment of the present invention will be described. in, figure 1 is a schematic diagram showing the structure of the cantilever; figure 2 is a schematic diagram showing the stress distribution during heating; Figure 8 is a structural schematic diagram showing a head suspension assembly having a plurality of head gimbal assemblies equipped with suspension parts; Figure 9A schematic diagram showing a disk drive structure equipped with the magnetic head suspension assembly.

[0035] [structure]

[0036] exist figure 1 The middle table shows the shape of the flexible member 2 which is a partial suspension member on which the magnetic head slider 1 is mounted. Such as Figure 8 As shown, the flexible member 2 is fixed on the load bar 11 , and the load bar 11 is fixed on the base plate 12 to form the cantilever member 13 . Moreover, the suspension member 13 with this structure is f...

Embodiment 2

[0053] Below, refer to image 3 and Figure 4 A second embodiment of the present invention will be described. Compared with the case described in the first embodiment, the shape and position of the slit-shaped hole 24 formed in the tongue surface 21 in this embodiment are different.

[0054] [structure]

[0055] Such as image 3 As shown, in this embodiment, the tongue surface 21 is formed with slit-shaped holes 24 cut from both sides toward the center. That is, the slit-shaped hole 24 is cut from the side end of the tongue surface 21 and has an open shape at one end. In other words, the slit-shaped holes 24a, 24b that open respectively are formed from the vicinity of the center of the tongue surface 21 toward both side ends. Therefore, end portions 24aa, 24ba in the longitudinal direction of the slit are respectively formed near the center of the tongue surface 21, and the front end side and the rear end side of the tongue surface 21 are connected through the portion bet...

Embodiment 3

[0063] Below, refer to Figure 5 and Figure 6 A third embodiment of the present invention will be described. In this embodiment, the shape of the slit-shaped holes 22, 23, and 24 described in the first and second embodiments described above is combined.

[0064] [structure]

[0065] Such as Figure 5 As shown, four slit-shaped holes 22, 23 and 24 (24a, 24b) are formed on the tongue surface 21 in this embodiment. Specifically, at first, near the front end (root) and the rear end of the tongue surface 21, respectively, on the side end surface of the tongue surface 21 as described in Embodiment 1, a closed structure having end portions 22a, 22b and 23a, 23b is formed. Formula slit-like holes 22,23. In addition, a pair of open-ended slit-shaped holes 24 (24a, 24b) are formed in two parts from the inner part in the vicinity of the center of the tongue surface 21 in the longitudinal direction.

[0066] Thus, by forming a plurality of slit-shaped holes (closed slit-shaped hole...

Abstract

There is provided a suspension capable of suppressing deformation of a magnetic head slider mounted thereon. At the same time, there are provided high-quality head gimbal assembly and hard disk drive capable of achieving stable writing and reading of data. It is a suspension comprising a tongue face for mounting a magnetic head slider, wherein a deformation-difference absorbing device is provided on the tongue face for absorbing a difference between thermal deformations of the tongue face and the magnetic head slider.

Description

technical field [0001] The present invention relates to a suspension on which a magnetic head slider is mounted, and more particularly to a suspension capable of suppressing deformation of the mounted magnetic head slider. In addition, the present invention also relates to a head gimbal assembly and a hard disk drive provided with the suspension member. Background technique [0002] A head gimbal assembly mounted on a hard disk drive includes a suspension on which a head slider for reading and writing data to a magnetic disk is mounted. Moreover, the suspension has a flexure 102 on which the head slider 101 is directly installed, and the structure of the front end of the flexure 102 is as follows: Figure 10 shown. here, Figure 10 A is a schematic diagram showing the side of the flexible member 102 where the magnetic head slider is installed, Figure 10 B is a schematic view showing the back side of the flexible member 102 . [0003] Such as Figure 10 As shown in A, the ...
