A magnetic head slider for use with a magnetic recording medium has a bearing surface which opposes to the magnetic recording medium and generates a pneumatic bearing effect for floating the magnetic head slider above a surface of the magnetic recording medium. The bearing surface includes a tapered surface portion constituting an air entrance and a flat rail portion connected to the tapered surface portion. The magnetic head slider has vent holes formed in the flat rail portion penetrating through the magnetic head slider from the flat rail portions to an end surface of the slider opposite to the magnetic recording medium.
