摘要： A magnetic head supporting mechanism includes a slider fixed to a slider spacer which is in turn fixed to a gimbal via a single area which is smaller than a contact area between the slider spacer and the gimbal so that the variation in the flying height of the slider is reduced and the positioning error due to the positional shifting of the head is also reduced. With this arrangement, it is possible to achieve a high-capacity magnetic disk storage device capable of operating at a high speed.

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.

摘要： A flying head slider utilizing a negative pressure according to the invention has a front end, a rear end, and an air bearing surface directed to face a rotating recording medium. The air bearing surface includes a pair of side rails extending on both sides of the air bearing surface from the front end in the longitudinal direction of the slider, a center rail provided at the center of the air bearing surface in the transverse direction and extending from the front end to the rear end in the longitudinal direction of the slider, a cross rail extending in the transverse direction of the slider to connect the pair of side rails and the center rail to each other near the front end, a pair of recesses defined by the pair of side rails, the center rail and the cross rail, communicating grooves for communicating the pair of recesses with the front end, and a head mounted on a rear end surface of the center rail. The pair of side rails, the center rail and the cross rail lie substantially in the same plane. The pair of side rails are spaced from the rear end and are terminated at oblique edges in agreement with oblique lines extending from side edges of the slider to the center of the center rail at its rear end. The pair of side rails each has a width shape which is gradually narrowed from the front end toward a narrow portion located in a vicinity of a center of the slider, and is gradually spread from the narrow portion toward the rear end. The center rail is extended from the front end with substantially a constant width, followed by a width shape gradually spreading toward the rear end.
