う問題があった。Conventional magnetic transducers, as described in Japanese Unexamined Patent Publication No. 49-12 [Phase] 514, form a continuous lift-generating floating surface and move the surface of the disk at a constant inclination. It was floating above. However, the slider above is well polished. Although this method is suitable for floating above the disk surface, no consideration has been given to dust that accumulates on the disk surface. If dust gets into the narrow space between the slider and the disk, it will stick to the head or disk due to frictional heat, change the floating posture of the slider, cause direct contact between the disk and the head, or There was a problem in that the disk surface was scraped, which in turn caused the head to crash.

提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic head slider that is less prone to head crashes caused by dust deposited on a disk.
本発明は、上記目的を達成するために１分離した揚力発

きる。そのため、従来のスライダーに比べ。An embodiment of the present invention will be described below with reference to FIG. According to the present invention, the buoyancy force generating surfaces 2.2' are provided separated by one, thereby making the buoyancy force of the conventional second buoyancy force generating surface 5 unnecessary. As shown in Figure 2, the conventional slider maintains the relationship ho > hl, generates a buoyancy force on the slider surface 5, and reduces the load Wo.
It was floating while maintaining its balance. In the configuration of the present invention, as shown in Fig. 3, the levitation generating surfaces 2 and 2' are provided separately, so that the balance with the load We can be maintained stably while maintaining the state of shO' to hl. Can be floated. Therefore, compared to traditional sliders.

、浮上刃を発生する必要がないため。ho >ho', which creates the effect of making it difficult for dust to get mixed in. Further, when the second slider surface 5 is configured with one piece, there is no need to generate floating blades.
従来の長さ／、に比べ２１’を短くすることができ。21' can be made shorter than the conventional length.
塵埃が排除されやすい効果が生まれる。This creates the effect that dust is easily removed.
本発明によれば、塵埃のまき込みを軽減することができ

。According to the present invention, the incorporation of dust can be reduced, and the dust can be easily removed, so that there is an effect of improving the reliability against head crashes of the disk device.
