A magnetic disk device having a magnetic disk, a magnetic head slider with a magnetic head mounted thereon and having a first surface, a second surface, a third surface and a fourth surface which are formed sequentially from an adjacent side to the magnetic disk, and a gap of a magnetic head arranged on the first surface. A relation of d1<D2<D3 is established where d1 is a depth from the first surface to the second surface, d2 is a depth from the second surface to the third surface, and d3 is a depth from the third surface to the fourth surface. The magnetic head slider has a floating pitch attitude of at least 50 micro-radians with respect to the magnetic disk.
