PURPOSE:To heighten the rigidity of a loading beam and to suppress the vibration of the loading beam due to windage disturbance according to the rotation of a recording medium, by providing at least one auxiliary flange element along a direction almost crossing orthogonally to the longitudinal direction of the loading beam at the flat part of the loading beam. CONSTITUTION:A head supporting device is constituted of the loading beam 2 which puts load on a magnetic head 3, a gimbal elastic spring element 1 whose one end is coupled with the loading beam 2 and supports the magnetic head 3, and a load flat spring part 9 which applies pressing load on the magnetic head 3. The loading beam 2 is provided with an elongated flat part 5 and flanges 4 at both sides of the part, and at the root part of the flat part 5, an auxiliary flange 6 is provided in a direction crossing with the longitudinal direction by cutting and bending the flat part 5. Therefore, the twisting and flexural rigidity of the loading beam 2 can be heightened, and the amplitude vibration of the loading beam 2 due to air flow according to the rotation of a recording disk can be suppressed at a low level, which stabilizes the floating of the magnetic head 3.
