Head slider

摘要

Associated with decrease in flying height of a magnetic head slider, there arises a problem of destabilization of flying of a slider due to attachment of contamination to a flying surface of a magnetic head slider. Ions exerting an effect of decreasing surface energy are implanted in the whole surface of a flying surface of a magnetic head slider 1 except for a front rail surface 4 and a center rail surface 7. According to this, contamination is prevented from being attached to a front step bearing surface 5, a side step bearing surface 6, a center step bearing surface 8 and a negative pressure groove 9 where contamination is particularly liable to be attached in the flying surface of the magnetic head slider, so as to suppress destabilization in flying of the slider. The ion implantation in the whole surface of the flying surface of the magnetic head slider increases the surface roughness of the front rail surface 4 and the center rail surface 7, but in the case where ions are implanted by excepting the front rail surface 4 and the center rail surface 7 as in the invention, contamination may be effectively prevented from being attached to the flying surface without increase in surface roughness, whereby destabilization in flying of the slider may be suppressed.
