A slider 3a is disposed to face a disk-like recording medium and enabled to support a read/write head. The slider 3a has an air bearing surface formed between a leading edge 10 and a trailing edge 11; side rails 20 and 21 formed on the air bearing surface almost like a U-letter so as to dispose its tip at the trailing edge side 11; a cross rail 22; and a pair of landing pads 30a and 31a formed between the tip of each of the side rails and the cross rail 20 to 22 and the trailing edge 11. One of the pair of landing pads 30a and 31a is formed as a convex surface at its side facing the rail of the landing pad 31a disposed at the outer periphery side of the disk-like recording medium while the slider is disposed so as to face the disk-like recording medium.
