Abstract: A pair of side pads, which are arranged to face each other by having a negative pressure generating part in the direction orthogonal to an air flow direction of a slider therebetween, are made to have three or more steps, respectively. Of the respective surfaces having the plural steps, the surfaces having a highest height respectively are not subject to a milling, and the respective surfaces of having plural steps are made to gradually have a deeper cavity depth as the surface comes closer to the air inflow end. Further, it is also effective for improving the efficiency in positive pressure generation to surround the second side pad region partially by the region of the surface being not subject to the milling, and to surround the third side pad region partially by the second surface region.

Abstract: A magnetic head structure is formed on an air-bearing surface thereof including first, second and third surfaces located in order in a height direction from a level closest to the magnetic recording medium so as to form negative and positive pressure-generating regions. The structure includes a first positive pressure-generating region having the second and first surfaces formed at a central portion along a longitudinal direction thereof, a first negative pressure-generating region having the third surface formed on a side of an air inlet edge with respect to the first positive pressure-generating region and a second negative pressure-generating region having the third surface formed on a side of an air outlet edge with respect to the first positive pressure-generating region.

Abstract: A head gimbal assembly is prepared, a proximal end portion of a suspension therein is supported at a given mounting height above a surface of an inspection disk, and a magnetic head of the head suspension is brought into contact with the surface of the inspection disk. In this state, the inspection disk is rotated, and separation of the magnetic head from the inspection disk surface is detected with the mounting height of the suspension and/or the rotational frequency of the inspection disk changed. The mounting height and the rotational frequency of the inspection disk are converted into a contact force of the magnetic head to measure the contact force when the head is separated from the inspection disk surface.
