ABSTRACT:
A magnetic head slider includes a floating surface that is opposed to a disk during the use of the magnetic head slider and that has a front part and a rear part with respect to the direction of rotation of the disk, and an electromagnetic transducer element. A front rail extending in the transverse direction and a pair of rear rails are laid on the floating surface. A plurality of first projections is formed on the front side and the rear side of the front rail. A plurality of second projections is formed behind the plurality of first projections. When the disk is stopped, the plurality of first projections is stationed on the disk but the floating surface is not in contact with the disk. The height of each of the plurality of second projections is smaller than the height of each of the plurality of first projections. When the magnetic head slider is employed in a contact start/stop (CSS) type disk drive, the plurality of second projections prevents the rear end of the floating surface from coming into contact with the disk.
