摘要： A magnetic head slider suitable for a disk drive measuring 1.8 inches or less in disk size incorporates preventive measures against the decreases in lifting force that occur in small sliders with a slider width of 0.8 mm or less. The present invention improves the inclination margins of the flying slider in a rolling direction at the lowest flying point, and achieves low flying height and stable flying. The slider is constructed with stepped surfaces on the slider's leading-side flying surface formed up of shallow-grooved surfaces and a deep-grooved surface so that a trailing-side width W2 between the stepped surfaces is smaller than a leading-side width W1.

摘要： Embodiments of the invention provide solutions to a problem, in which a reduced peripheral speed resulting from a trend toward a magnetic disk having a smaller diameter makes it more and more difficult to achieve a lifting force that allows a magnetic head slider to fly stably. According to one embodiment, in a magnetic head slider comprising a leading edge, a trailing edge, and an air bearing surface, the air bearing surface includes a plurality of leading side rail surfaces, a trailing side rail surface disposed in the same plane as the leading side rail surfaces and having a magnetic head mounted thereon, a stepped bearing surface having a predetermined depth δ1 from the leading side rail surface, and a negative-pressure groove surface having a depth δ2 from the leading side rail surface, the depth δ2 being even deeper than the stepped bearing surface. The leading side rail surfaces include first stepped surfaces having a predetermined height h1 and second stepped surfaces having a predetermined height h2 from the first stepped surfaces, the first stepped surfaces and the second stepped surfaces having continuity in a longitudinal direction of the magnetic head slider.

摘要： A magnetic disk unit includes a magnetic disk attached to a spindle so as to be rotatable, a slider having a magnetic head for reading/writing data onto/from the magnetic disk, a suspension for providing the slider with a predetermined load, and an actuator arm for positioning the slider attached to the suspension on the magnetic disk. A first pad including the magnetic head and second pads including no magnetic heads are disposed on an air bearing surface of the slider. During rotation of said magnetic disk, a part of the first pad keeps in contact with the magnetic disk. A load point of the suspension with respect to the slider is positioned between a leading edge of the slider and a position located at a distance equivalent to substantially 0.42 times a whole length of the slider from the leading edge of the slider.

A load point of the suspension with respect to the slider is positioned between a leading edge of the slider and a position located at a distance equivalent to substantially 0.42 times a whole length of the slider from the leading edge of the slider. When the slider is seek-positioned on a certain track on the magnetic disk, a frictional force exerted between the first pad of the slider and the magnetic disk is smaller than a product of lateral stiffness of the suspension in a seeking direction and a track width.
