A magnetic head structure has a coil and a magnetic pole allowing a magnetic flux generated by the coil to be transmitted therethrough and forming a magnetic gap. An insulating layer (32) surrounds the coil, and a protective layer (34) covers the insulating layer and the magnetic pole. The insulating layer has a volume equal to or greater than a value which is determined with respect to a thickness of the protective layer. It is preferable to increase the volume of the insulating layer as the thickness of the protective layer is made greater. By increasing the volume of the insulating layer, the protrusion of a portion of a floating surface of the magnetic head slider near the magnetic pole, toward the disk, is reduced.
