摘要： 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.

摘要： According to one embodiment, a slider of a magnetic head is provided with a negative-pressure cavity formed in a facing surface, a leading step portion situated on the upstream side of the negative-pressure cavity, a pair of side portions opposed to each other, a trailing step portion situated on the outlet end side of the negative-pressure cavity, and a pair of embossed portions formed on the facing surface so as to project from the negative-pressure cavity and provided on the outlet side of the negative-pressure cavity with respect to an airflow. The embossed portions individually extend along a second direction so as to be situated individually on the opposite sides of the trailing step portion and are formed so as to be lower than the trailing step portion with respect to the negative-pressure cavity and flush with an outlet-side end surface of the slider.
