摘要： Embodiments of the present invention provide a slider that may suppress contamination from being attached to the flying surface of the slider without influence on reduction of the flying height of the slider. Ions exerting an effect of decreasing surface energy are implanted in the whole surface of a flying surface of a magnetic head slider except for a front rail surface and a center rail surface. According to this, contamination is prevented from being attached to a front step bearing surface, a side step bearing surface, a center step bearing surface and a negative pressure groove 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.

摘要： Embodiments of the present invention provide a slider that may suppress contamination from being attached to the flying surface of the slider without influence on reduction of the flying height of the slider, and a method for producing the same. According to one embodiment, ions exerting an effect of decreasing surface energy are implanted in the whole surface of a flying surface of a magnetic head slider except for a front rail surface and a center rail surface. According to this, contamination is prevented from being attached to a front step bearing surface, a side step bearing surface, a center step bearing surface and a negative pressure groove 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 and the center rail surface, but in the case where ions are implanted by excepting the front rail surface and the center rail surface as in accordance with embodiments of 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.

摘要： A thin film magnetic head includes a three-step configuration including deep and shallow groove surfaces, a super shallow groove surface, and an air bearing surface, and also, island-shaped center rail is provided in the center of the air outflow end of the disk-facing air bearing surface having a boundary on the surface of base alumina between a head element portion and a substrate, without including the surface of the substrate. Further, by providing in the surface of the substrate the super shallow groove surface shallower than a shallow groove surface, an alumina recession between the surface of the substrate and the head element portion, produced in a shallow dual step sub ambient slider, can be eliminated. Magnetic spacing between the head of the head element portion and the magnetic layer of the disk can be thereby reduced.
