  • Patent number: 4853812
    Abstract: A magnetic head supporting structure includes a gimbal member which carries a core slider and which is provided with a loading projection, and a loading beam member having one end connected with the gimbal member and contacting the loading projection to urge the core slider towards a recording medium. The surface of the portion of the loading beam member contacting the loading projection is offset from the surface of the loading beam member connected with the gimbal member, to thereby reduce the height difference between the plane and the centroid of the core slider. The reduced height difference reduces the moment which acts on the core slider during movement thereof, thus enabling the core slider to stably float without inclination with respect to the magnetic recording surface.
