Abstract:
A magnetic disk unit including a magnetic disk attached to a spindle so as to be rotatable, a slider having a magnetic head for reading/writing data onto/from said magnetic disk, a suspension for providing said slider with a predetermined load, and an actuator arm for positioning said slider attached to said suspension on the magnetic disk, said magnetic disk unit comprising:a first pad disposed on an air bearing surface of said slider, said first pad including the magnetic head;second pads disposed on the air bearing surface of said slider, said second pads including no magnetic head and not being in contact with said magnetic disk;said first pad keeping in contact with said magnetic disk during rotation of said magnetic disk;a gimbal coupled to said suspension; whereina load point on said suspension positioned between a leading edge of said slider and a position located at a distance equivalent to substantially 0.42 times a whole length of said slider from the leading edge of the slider, said load point being matched with a center of impact in contacting said first pad with said magnetic disk, whereby a moment acts on the slider by applying the predetermined load upon the load point and also turns said gimbal by a predetermined angle in a direction as to move the first pad towards the magnetic disk.
