Magnetic head sliders having air-bearing surfaces designed to reduce the protrusion compensation effect. The magnetic head slider includes: at least one front pad located an upstream portion of the slider and operative to generate a lifting force; and a rear pad that is located downstream of the front pad and includes a load-carrying part, for generating a lifting force, and a head mounting part. The head mounting part is separated from the load-carrying part by a groove formed between the load-carrying part and the head mounting part. The head mounting part contains a heat source that generates heat energy and thereby causes a protrusion throw to form on the slider. The groove suppresses formation of the protrusion throw on the load-carrying part and thereby localizes the protrusion throw mostly in the area adjacent to the head mounting part.
