である。Next, the deposits on the rail surface can be easily removed by scraping them in the longitudinal direction of the rail. Therefore, FIG. 6 shows an embodiment in which the cleaning surface is provided with an appropriate roughness. This is an example in which the surface roughness 13 is applied to the arrow 11 indicating the movement of the magnetic head slider 1 at an inclined angle. When the magnetic head slider 1 moves in the direction of the arrow 11, the deposit 9 on the rail surface is scraped in the direction of the arrow 12 by the surface roughness (surface irregularity) 13 of the cleaning surface 3, and the movement of the rail in the longitudinal direction. Since the components are generated, the removal effect is improved. In addition to this, the material of the cleaning surface,
The hardness, roughness, roughness direction, and temperature are selected appropriately to increase the effect of scraping off the deposits, and the cleaning surface contains a solvent to chemically remove the deposits from the rail surface. The method of doing so can be easily added.

A lifter 14 for smoothly lifting and lowering the load arm 2 is added. Cleaning surface 3
FIG. 8 is a perspective view showing the vicinity of the lifter 14 and the lifter 14. The lifter 14 has a smooth slope, and moves the load arm 2 up and down smoothly by the radial movement 11 of the magnetic head slider 1. The cleaning surface 3 also has a smooth slope 15, and the magnetic head slider 1 is smoothly raised and lowered on the cleaning surface 3. The cleaning surface 3 has a function of removing the deposit 9 on the rail surface from the rail surface as in the case described above.

ができる。FIG. 9 is a side view seen from the direction A in FIG. 8 in order to show the relationship between the loading / unloading operation and the deposit removing operation. First, during recording and reproduction, the magnetic head slider 1 is on the surface of the magnetic disk 6. Next, when the magnetic head slider 1 is unloaded from the magnetic disk 6, the movement of the voice coil motor causes the magnetic head slider 1 to move in the direction of the arrow 11 (outer peripheral side of the disk). At this time, the load arm 2 rides on the slope of the lifter 14 so that the magnetic head slider 1 is lifted above the surface of the magnetic disk 6. After that, when further moving in the direction of the arrow 11, the magnetic head slider 1 rides on the slope 15 and is finally placed on the cleaning surface 3. Here, the load arm 2 is not in contact with the lifter 14. In this state, the deposit removing operation shown in FIGS. 3 and 6 is performed. Next, the magnetic head slider 1 is moved to the magnetic disk 6 again.
To load on, follow the reverse procedure. According to this mechanism, it is possible to provide both an L / UL mechanism for loading / unloading the magnetic head slider on the magnetic disk and a mechanism for cleaning the rail surface of the magnetic head slider.

So-called head crashes such as contact, sliding, and breakage can be prevented, and the flying height of the slider is reduced.
The magnetic recording density can be improved. In addition, it can be easily equipped at low cost without requiring a complicated mechanism.
