PURPOSE:To obtain a head slider having less dust sticking by providing a slot not reaching a flowing end along a lengthwise direction to an air bearing and providing a throughhole reaching a face except the air bearing face of the slider to an groove so as to attain excellent bearing dynamic characteristic and stable floating. CONSTITUTION:Two air bearing rails 5 as a floating means by the air bearing of a slider member 1 consist of a bearing tilting face 4 and a bearing plane part 3 formed to the gas intake side 5a. The both are separated into two while the flowout end 5b of the rails 5 is left by the groove 7 and the throughhole 8 reaching the rear part 1a of the air bearing rails 5 of the slider member 1 from the flowout end 7b of the slot 7 is provided. Nearly the same atmospheric pressure is provided to the groove 7 and the throughhole 8 and the pressure at the bearing plane up to the flowout end 7b after the groove 7 is small and the gas bearing rail 5 acts as the assembling of the two gas bearing rails. Thus, the bearing dynamic characteristic is excellent and stable floating is attained, then the head slider having less dust sticking is obtained.
