摘要： Embodiments of the invention enable the flying of a slider to be lowered and increase recording density with a simple configuration in a magnetic disk apparatus. In one embodiment, a magnetic disk apparatus comprises a magnetic disk including tracks for recording data; a magnetic head slider disposed with a magnetic head that flies over the rotating magnetic disk and records data to, or plays back data from, the magnetic disk; and a control device that controls the operation of the apparatus. Slider flying height data that vary inside the tracks are prerecorded in the tracks of the magnetic disk. The control device controls the operation of the magnetic head slider with respect to the magnetic disk on the basis of the slider flying height data recorded in the tracks

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 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 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.

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.
