しまい、エラーにつながるという問題があった。By the way, in the conventional information recording / reproducing apparatus, as shown in FIG. 7, a slider 5 provided with a signal converter (R / W gap) constituting the magnetic head 4 is provided. The anti-signal conversion portion surface 5a was adhered and fixed to the flexure 6 serving as a holder with the adhesive 13. However, according to the adhesive fixing means, the slider 5 may be warped due to the contraction of the adhesive 13 when the adhesive 13 dries. Further, due to the difference in the coefficient of thermal expansion between the flexure 6, slider 5 and adhesive 13, the slider 5 may warp (shown by the solid line in FIG. 6) due to temperature changes. That is, in the conventional information recording / reproducing apparatus, the coefficient of thermal expansion of these materials is, for example, 100 to 300 ° C.
When 304 is used, it is 17.3 × 10 to 6 1 / ° C., for a slider made of ferrite it is 11.5 × 10 to 6 1 / ° C., and for an ultraviolet curable adhesive it is 16 × 10 to 6 1 / ° C. As described above, since there is a difference in the coefficient of thermal expansion between the flexure 6, the slider 5, and the adhesive 13, the amount of contraction (or expansion) of each member differs due to temperature changes, and the slider 5 warps. When a warp occurs on the surface of the slider 5 facing the recording medium in this way, the R /
There is a problem in that the distance ΔFH between the W gap portion and the recording surface of the recording medium changes, the read or write level of the signal changes, leading to an error.

In FIGS. 3A and 3B, 24 is a flexure and 25 is a slider. On the rail 37 of the slider 25, a signal converter (R / W gap) (not shown) is formed at one end of the rail 37 with respect to the recording surface of the recording medium. The flexure 24 has slits 26, 26 notched in a rectangular frame shape leaving a pair of connecting portions, a rectangular opening 27 opened in the slits 26, 26, and opposing sides of the opening 27. And a slider fixing piece portion 28, which is bent from the above portion in an L shape. The slider 25 is fitted between the slider fixing pieces 28, 28,
Both side surfaces 25a, 25a are adhered to the slider fixing pieces 28, 28 with an adhesive 22, respectively, and the slider 25 is fixed to the flexure 24. In addition, FIG.
As shown in, the center of gravity G of the slider 25 and the holding position of the flexure 24 are fixed so as to substantially coincide with each other. Thereby, the posture of the slider 25 can be balanced.

響を及ぼさない。In this way, both side surfaces 25 of the slider 25 are
Since the adhesive 25 is affixed to the flexure 24 with a and 25a, the adhesive 22 is not applied to the surface (for example, the upper surface) parallel to the recording surface of the recording medium of the slider 25, so the recording medium of the slider 25 is contracted by the adhesive 22. No warpage occurs on the surface facing to. Also in the case of this embodiment, the contracting force of the adhesive 22 acts so as to cancel out, and the adhesive 22
Even if the contracting force is applied, it is in the surface direction of the slider 25, so that the slider 25 hardly warps. Further, since no member such as the flexure 24 is arranged on the upper surface of the slider 25, the device can be thinned by the thickness of the flexure 24. Further, since the center of gravity G of the slider 25 and the holding position of the flexure 24 are substantially aligned with each other, the posture of the slider 25 can be balanced.
When the slider 25 is transferred to a desired position on the recording surface of the recording medium, a roll direction generated on the slider 25 (see FIG.
The inclination in the direction of the arrow (b) can be suppressed, and the level of the read or write signal is not adversely affected.
