Abstract
An air-bearing head slider for supporting an electromagnetic transducer opposite to a rotating recording media or magnetic disk. A slider body has a surface having a leading or air-entry side and a trailing or air-delivery side. Two rails are provided on the surface of the slider body and has floating surfaces opposite to the rotating magnetic disk for generating a floating force. The two side rails extend along a direction of air flow generated by the rotation of the magnetic disk and define a relatively shallow groove between these two rails. The groove has a width-enlarged portion at which the width of the groove is enlarged, so that a negative pressure is generated in such a manner that the slider body is attracted to the rotating magnetic disk. Inclined surfaces are formed on the air-entry sides of the floating surfaces of the rails. An inclination angle of the inclined surface is not more than 3.degree. and not less than 0.5.degree. and a length of the inclined surface is not less than 50 .mu.m and not more than a half of a length of the rails in the direction of air flow.
