摘要： A magnetic disk drive includes a magnetic recording medium and a magnetic head slider adapted to fly over a surface of a magnetic recording medium and read or write information. The magnetic head slider includes a slider air bearing surface and a magnetic transducer. The slider air bearing surface includes a front pad having front rail surfaces and front step bearing surfaces, a rear pad having a rear rail surface and a rear step bearing surface, and a negative-pressure groove interposed between the front pad and the rear pad. A vibration suppressing groove is formed in the rear rail surface so as to be deeper than the rear rail surface and to be closed at its periphery. The vibration suppressing groove quickly damps out translational and pitching vibrations in the flying height direction of the magnetic head slider while stabilizing its flying.

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： A magnetic head slider has a recess portion recessed with respect to the center rail. The recess portion has a spherical or oval-spherical projection, which includes a read element and a write element disposed in the recess portion. The recess portion may prevent increasing flying height of a slider base due to projection height h may be suppressed, and may secures higher air film stiffness, so that consequently flying stability of the slider may be improved.

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： Embodiments of the present invention provide a head slider that suppresses accumulation of lubricant droplets on an air-bearing surface due to a backflow, and thus improves reliability of a disk drive. According to one embodiment, a lubricant droplet being adhered to a head slider and accumulated thereon, which are caused by extremely low flying height of the head slider, are prevented from falling onto a recording medium. When velocity of a recording medium at a position where the head slider faces the recording medium is assumed to be v, step depth δ4 at an outflow side of an outflow side rail satisfies, δ4≦0.1125*log10(v)+0.019.

摘要： Embodiments in accordance with the present invention provide a magnetic head slider capable of securing a larger flying margin even when position variations occur at the time of flying. Embodiments of the present invention also provide a magnetic head slider having an excellent flying following capability. A read element and a write element of a magnetic head slider are arranged on a spherical or ellipsoidal projection and this projection is formed on a thin film magnetic head part. This may prevent a flying margin from being reduced by variations in flying position and may prevent a manufacturing step from being caused on the spherical or ellipsoidal projection. Moreover, by making the constituent ratio of the thin film magnetic head part on an air-bearing surface of the magnetic head slider 100 to be 7% or more, the read element and the write element are arranged at a pressure center position on the center rail surface of the air-bearing surface. This may enhance a following capability when the slider flies.
