Abstract
A head slider has small friction force even if the head slider comes in contact with a magnetic disk having a smooth surface at high speed. The vibration is also low and wear resistance is high. The head slider is provided with plural air bearing surfaces for floating over the magnetic disk or one or more lubricant bearing surfaces for smoothly gliding over the magnetic disk. A slope angle on the front side of the bearing surface in the traveling direction of the head slider is larger than a slope angle on the rear side of the bearing surface in the vicinity of a contact part of the bearing surface that may come in contact with the magnetic disk.
