Abstract: A floating thing-film magnetic head and method of producing the same is provided. A floating thin-film magnetic head includes a slider that is floated from a surface of a rotating recording medium by airflow generated over the surface of the recording medium. A thin-film magnetic head element formed on an air-outflow end surface of the slider. A crown is formed on a medium-facing surface formed of the bottom surfaces of the slider and the thin-film magnetic head element that protrudes in a section that includes an air-inflow end and an air-outflow end of the slider. The crown includes a large-diameter crown with a large curvature radius that forms a central portion of the medium-facing surface that excludes the air-inflow end and the air-outflow end. A small-diameter crown forms portions of the medium-facing surface that correspond to the air-inflow end and the air-outflow end.

Abstract: A magnetic head includes a metal plate having a conductive pattern, and a slider having a head element and a connecting terminal electrically connected to the head element, and fixed on the metal plate. The connecting terminal and the conductive pattern are connected by ultrasonically bonding a ball bump thereto. The ball bump has on its surface a projecting portion extending in the direction that links the connecting terminal and the conductive pattern. A bonding capillary for use in the ultrasonic bonding includes a tip section having a through hole for passing a wire therethrough. The tip section also has a recessed portion centered on the through hole, and a groove that reaches the outer surface of the tip section across the center of the recessed portion.

Abstract: For the purpose of obtaining better flexibility in a case where a flexible cable is used for the wiring of a head main body of a floating type magnetic head than the flexibility obtained in a case where a copper wire is used for the same to maintain satisfactory degree of freedom of the head main body, the equation shown below shall be satisfied:W/L.ltoreq.-15(A.times.Dc+Dp)+0.5whereW=width of a band-shaped portion to be a bending portion of a flexible cable to be used for the wiring of the head main body,L=length of the band-shaped portion,Dp=thickness of the cable base material of the above portion,Dc=thickness of the conductor layer of the above portion,A=area ratio of the conductor layer to the cable base material.
