Abstract

A magnetic head slider includes a magnetic head for recording/reproducing information from/into a magnetic disk and a slider on which the magnetic head is mounted. The slider has a first surface and a second surface provided at an air-outflow side at positions with respect to the first surface, and projections having a cylindrical shape are provided on a third surface at an air-inflow side at positions with respect to said first surface.

Claims (20)

1. A magnetic head slider comprising a magnetic head for recording/reproducing information from/into a magnetic disk and a slider on which said magnetic head is mounted, wherein said slider has a first surface and a second surface provided at an air-outflow side at positions with respect to said first surface, and projections having a cylindrical shape are provided on a third surface at an air-inflow side at positions with respect to said first surface.

2. A magnetic head slider according to claim 1 , wherein distal ends of said projections are formed into a semi-spherical shape or a shape having a curvature.

3. A magnetic head slider according to claim 1 , wherein said third surface is lower than said first surface.

4. A magnetic head slider according to claim 3 , wherein said projections have a height which is higher than or equal to a height of said first surface relative to said third surface.

5. A magnetic head slider according to claim 1 , wherein said first surface and said third surface constitute a flying pad.

6. A magnetic head slider according to claim 1 , wherein distal ends of said projections are formed into a planar surface.

7. A magnetic disk apparatus comprising a magnetic head slider including a magnetic head for recording/reproducing information from/into a magnetic disk and a slider on which said magnetic head is mounted, wherein said slider has a first surface and a second surface provided at an air-outflow side at positions with respect to said first surface, and projections having a cylindrical shape are provided on a third surface at an air-inflow side at positions with respect to said first surface.

8. A magnetic disk apparatus according to claim 7 , wherein distal ends of said projections are formed into a semi-spherical shape or a shape having a curvature.

9. A magnetic disk apparatus according to claim 7 , wherein said third surface is lower than said first surface.

10. A magnetic disk apparatus according to claim 9 , wherein said projections have a height which is higher than or equal to a height of said first surface relative to said third surface.

11. A magnetic disk apparatus according to claim 7 , wherein said first surface and said third surface constitute a flying pad.

12. A magnetic disk apparatus according to claim 7 , wherein distal ends of said projections are formed into a planar surface.

13. A magnetic head slider comprising a magnetic head for recording/reproducing information from/into a magnetic disk and a slider on which said magnetic head is mounted, wherein said slider has a first surface and a second surface provided at an air-outflow side at positions with respect to said first surface, and projections are provided on a third surface at an air-inflow side at positions with respect to said first surface and distal ends of said projections are formed into a semi-spherical shape or a shape having a curvature.

14. A magnetic head slider according to claim 13 , wherein said third surface is lower than said first surface.

15. A magnetic head slider according to claim 14 , wherein said projections have a height which is higher than or equal to a height of said first surface relative to said third surface.

16. A magnetic head slider according to claim 13 , wherein said first surface and said third surface constitute a flying pad.

17. A magnetic disk apparatus comprising a magnetic head slider including a magnetic head for recording/reproducing information from/into a magnetic disk and a slider on which said magnetic head is mounted, wherein said slider has a first surface and a second surface provided at an air-outflow side at positions with respect to said first surface, and projections are provided on a third surface at an air-inflow side at positions with respect to said first surface and distal ends of said projections are formed into a semi-spherical shape or a shape having a curvature.

18. A magnetic disk apparatus according to claim 17 , wherein said third surface is lower than said first surface.

19. A magnetic disk apparatus according to claim 18 , wherein said projections have a height which is higher than or equal to a height of said first surface relative to said third surface.

20. A magnetic disk apparatus according to claim 17 , wherein said first surface and said third surface constitute a flying pad.
