Abstract:
A slider for receiving air pressure at a surface facing a medium, said slider having a leading edge, a trailing edge, a first side and a second side, said surface comprising:a base surface extending from said leading edge to said trailing edge;a front portion having a height above said base surface, extending from the leading edge toward the trailing edge, and widening from the leading edge toward the trailing edge;a first positive pressure generating portion abutting said front portion, extending toward said trailing edge, having a first height above said front portion;a second positive pressure generating portion abutting said front portion, extending toward said trailing edge, having a second height above said front portion, said second height being essentially equal to said first height;a first negative pressure generating portion abutting said first positive pressure generating portion, extending toward said trailing edge, and having a third height below said first positive pressure generating portion;a second negative pressure generating portion abutting said second positive pressure generating portion, extending toward said trailing edge, and having a fourth height below said second positive pressure generating portion, said fourth height being essentially equal to said third height;a third positive pressure generating portion abutting said first negative pressure generating portion, extending toward said trailing edge, having a fifth height above said first negative pressure generating portion; anda fourth positive pressure generating portion abutting said second negative pressure generating portion, extending toward said trailing edge, having a sixth height above said second negative pressure generating portion, said sixth height being essentially equal to said fifth height.
