PURPOSE:To hold variation in floating height small by providing a positive pressure generation part that has a part where the gap to a disk surface narrows down gradually in an air inflow direction at two front and rear places in the air inflow direction, and a negative pressure generation part which becomes wider gradually in the air inflow direction between the positive pressure generation parts. CONSTITUTION:The positive pressure generation parts 8c and 8d which have lengths l1 and l2 and a width W consists of floating surfaces 2c and 2d and slope surfaces 3c and 3d for air inflow. The pressure distribution in the center of a floating head slider 1 in the direction of the length l has positive pressure parts at the front and rear parts shown by the lengths l1 and l2 and a negative pressure part shown by a length l3 between them. Then, the longitudinal/lateral ratios W/l1 and W/l2 of the substantial positive generation parts 8c and 8d are much larger than a conventional longitudinal/lateral ratio W/l at both front and rear parts. Therefore, the variation in the floating height when the angle included by the direction of the air inflow and the lengthwise direction of the floating head slider varies is held less than before. |
