ABSTRACT:
For resiliently supporting a transducer head on a carrier member, such as a head carriage or a load arm pivoted thereon, that is movable radially of a flexible magnectic disk, a flexure seat is provided which is fabricated from resilient sheet metal material. The flexure seat comprises a central portion of circular or polygonal shape on which the transducer head is to be fixedly mounted, a peripheral portion surrounding the central portion and to be secured to the head carrier member, and several bridge portions interconnecting the central and peripheral portions at points angularly spaced from one another about the center of the central portion. Each bridge portion comprises two deflective strips of approximately the same length extending along the periphery of the central portion substantially in parallel relation to each other and joined to each other each at one extremity thereof. The other extremities of the deflective strips are joined respectively to the central portion and to the peripheral portion. So configured, the bridge portions permit the transducer head on the central portion to be resiliently displaced only in a direction normal to the principal plane of the flexure seat and, therefore, to that of the magnetic disk.
