Patent ID: 7652846

Claim:
A magnetic head slider comprising: a slider; and a magnetic element for recording and/or reproduction, which is provided on an air outflow end side of said slider; wherein, with a direction toward the air outflow end side from an air inflow end side of said slider as a vertical direction, and a direction intersecting with said vertical direction as a lateral direction a face of said slider facing a disk includes raised faces raised toward a disk direction from bottom faces which are negative pressure generating faces, said raised faces comprises: a magnetic element face, and the surface of said magnetic element is exposed on said air outflow end side; an air inflow end side raised face raised with the same height as said magnetic element face and provided closer to said air inflow end side than said magnetic element face; and a pair of rail faces disposed in opposing with a gap therebetween in the lateral direction, said rail faces connect said magnetic element face and said air inflow end side raised face and are raised with the same height as said magnetic element face and said air inflow end side raised face; wherein said negative pressure generating faces are divided in said lateral direction by said pair of rail faces, said each of divided negative pressure generating faces comprise: a first negative pressure generating face provided on said air outflow end side, and a second negative pressure generating face provided between said first negative pressure generating face and said air inflow end side raised face; wherein said first negative pressure generating face has negative pressure (absolute value) greater than said second negative pressure generating face; and wherein each of said first and second negative pressure generating faces includes the bottom face of a groove portion surrounded with raised walls at said air inflow side and both sides of said lateral direction.
