Abstract
A magnetic head structure capable of reducing the quantity of protrusion of a portion of a floating surface, at which a coil is located, toward a disk has been disclosed. The head comprises a coil, a magnetic poleallowing a magnetic flux generated by the coil to transmit therethrough and forming a magnetic gap, an insulating layersurrounding the coil, and a protective filmcovering the insulating layer and the magnetic pole and, if a first direction is defined as that in which the side of the floating surfaceof the magnetic head structure extends when viewed in the direction in which the coil, the magnetic pole, the insulating layer, and the protective film are laminated, and a second direction is defined as that perpendicular to the first direction, the ratio of the maximum length of the insulating layer in the first direction to that in the second direction is equal to or greater than 1.5.
