Abstract 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.
