摘要： A magnetic storage apparatus includes a substantially non-flexible magnetic recording medium, a magnetic head slider having a reading/writing element mounted therein and liquid lubricant provided on the surface of the magnetic recording medium. The liquid lubricant is a liquid in a Newtonian range having a viscosity which is substantially constant irrespective of a shear rate or a liquid having the property that the actual viscosity is increased with increase of the shear rate. The magnetic head slider maintains a gap between the slider and the magnetic recording medium to perform reading and writing while being moved on the liquid lubricant intermittently or continuously in a contact manner with the liquid lubricant. There is provided a device for maintaining a constant flying height even if a movement speed is varied, which flying height is represented by the size of the gap. Thus, the magnetic storage apparatus of the liquid bearing system or the contact system has only very small forces such as liquid drag force and friction force or sticking force and is capable of performing stable slider movement, performing high-speed seeking operation with high reliability and performing high-density recording.

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.

摘要： A decrease in the lift-up degree of the outflow end of a slider at an altitude of 3,000 m is set to be less than 2 nm or to be zero in order to set the lift-up degree of the outflow end to be less than 10 nm. There is provided a magnetic disc apparatus in which the action point of positive pressure is shifted toward the inflow end but the action point of negative pressure is shifted toward the outflow end so as to enhance the influence upon the outflow end by the negative pressure in order to effect an action in the increasing direction of the lift-up degree of the outflow end when the pressure is reduced. Further, it is possible to increase the lift-up degree of the outflow end when the pressure is decreased. The action point of the equivalent load is offset from the action point of positive pressure toward the inflow end, and the distance between the action point of the positive pressure and the action point of the equivalent load point is set to be greater than 0.1 times as large as the overall slider length.
