摘要： A magnetic disc apparatus includes a magnetic disc, a slider incorporating lifting rails or lifting pads, a magnetic head provided to a lifting rail or a lifting pad on the outflow end side, a suspension supporting the slider, and a carriage attached to the suspension. The slider has an inverted stepped wall formed in a shape such that it is caved in a direction from the inflow end to the outflow end of the slider, and a bleed surface formed at the outflow end side of the inverted stepped wall and caved from the lifting rails or the lifting pads. An action point of an equivalent load is located offset from the inverted stepped wall of the slider toward the inflow end of the slider.

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.

摘要： A magnetic head slider mounted on a magnetic disk unit for supporting a magnetic head that writes and reads information to and from a magnetic disk is constructed such that a depth δs1 from the surfaces of leading and trailing pads, which come into contact with a medium surface when the disk is at rest, to stepped surfaces formed on the air inflow side of the leading pads, a depth δs2 from the contact surfaces to stepped surfaces formed on the air inflow side of the trailing pad and a step depth δs3 from the contact surfaces to the surfaces of side rails are in a relation of δs1≦δs2≦δs3. With this arrangement, the slider can follow the waved medium surface at a low flying height with a small flying height fluctuation, thus realizing high density recording, high reliability and reduced cost of the magnetic disk unit.

摘要： A magnetic disk device and a flying slider, having a magnetic head for reading and writing information, are disclosed. The magnetic head slider includes flying pads of a stepped configuration for flying the slider, and each of the flying pads has a flat surface portion and a step surface recessed from this flat surface portion through a microscopic step. Microscopic projections are formed on the step surface. The height of the microscopic projections are higher than or substantially equal to the height of the step. With this construction, the slider is less liable to be turned to lean forward because of the provision of the microscopic projections, and beside a front edge of the step surface will not damage a magnetic disk surface. A variation of the flying height can be reduced by a negative pressure produced at the rear side of each microscopic projection. Therefore, there can be provided the magnetic disk device having high reliability and a large capacity.

摘要： A head element is made into contact with the surface of a recording medium so as to realize a float-up degree of 5 nm. Accordingly, a slider incorporating the head element for recording and reproducing data to and from the recording medium is provided thereon with a plurality of pads having step parts, and one of the plurality of pads, on which the head element is mounted, has a height which is less than that of the other pads. Thus, the pads other than the pad on which the head element is mounted are floated up while the pad on which the head element is mounted is stably made into contact with the surface of the recoding medium by means of a meniscus suction force and a damping action of lubricant applied on the surface of the recording medium.
