A magnetic recording head for reading and writing information with respect to a rotating disk medium includes a pad having a working surface which contacts the recording medium. The pad has a leading edge and a trailing edge with the leading edge facing in the general direction of relative motion between the head and the medium. The ledge has a narrower width than the trailing edge so as to reduce the effort of debris accumulation at the disk-head interface. The narrower leading edge allows the head to deflect oncoming debris as the head traverses the surface of the rotating magnetic medium.

Magnetic head slider with resistance to debris accumulation

A method of texturing the slider surface of a magnetic head, or the surface of a disk, with a laser. The laser is focused onto the hard disk drive component and a groove is ablated from the working surface. The steps of focusing and ablating can be repeated to create a pattern of grooves in the head and/or disk. The grooves are defined by a wall(s) that is perpendicular to a bottom surface of the groove.
