ABSTRACT:
A magnetic head slider (1) has a first rail (20) with a first air bearing surface, a second rail (25) with a second air bearing surface and further a third rail (15) with a third air bearing surface. The third rail is formed between the first rail (20) and the second rail (25). On both sides of the third air bearing surface (16), a first air pressurization part (17) and a second air pressurization part (18) are formed sunk by respective depths. When the skew angle ".theta." occurs, appropriate pressurized air flows are generated by the first air pressurization part (17) and the second air pressurization part (18) to compensate for the lifting force.
