Abstract
A magnetic head supporting device for supporting at least one magnetic head in contact with a flexible magnetic disk so as to record and reproduce signals in and from the flexible magnetic disk. The magnetic head supporting device comprises a gimbal spring having a central portion to which the magnetic head is secured at one side thereof; and a pivot which contacts on the opposite side of the central portion of the gimbal spring so as to support the center of the magnetic head through the intermediary of the gimbal spring. The gimbal spring includes an intermediate frame portion which supports the central portion in such a manner as to impart thereto a degree of freedom of rotation in the circumferential direction or in the radial direction of the magnetic disk, and an outer holding portion which supports the intermediate frame portion in such a manner as to impart thereto a degree of freedom of rotation in the direction perpendicular to the direction of freedom of rotation imparted by the intermeidate frame portion to the central portion. The width of parts of the intermediate frame portions extending in parallel to the direction of running of the surface of the magnetic disk, as measured in the direction perpendicular to the running direction, is determined to be smaller in the upstream portion of the intermediate frame portion than in the downstream portion of the same as viewed in the direction of running of the surfacae of the magnetic disk.
