Abstract
The present invention is directed to a slider, a head, a head device and a read/write apparatus that are extremely effective for achieving high density writing and an increase in the storage capacity. The slider comprises a front flat surface, a first positive pressure generating portion, a second positive pressure generating portion and a first negative pressure generating portion. The front flat surface, which is provided starting at a leading edge, ends at an intermediate point along a lengthwise direction. The first and second positive pressure generating portions have flat surfaces which are essentially of equal heights and are positioned separated from each other over a distance at two sides in a widthwise direction running perpendicular to a lengthwise direction, with edges at one end located toward the leading edge forming step faces rising up from the front flat surface in a step. The first negative pressure generating portion is provided behind the front flat surface relative to the airflow direction and has a base surface with a height which is lower than the height of the front flat surface.
