Abstract: A cantilevered beam assembly with a maximum resonance frequency is adaptable for supporting a transducer for use with a random access flexible disk file. The cantilevered beam assembly includes a first cantilevered member and a second elongated member coupled at one end by a flexible joint to the free end of the first cantilevered member. When used with a flexible disk file system, a magnetic transducer is seated on the second end of the elongated member while said elongated member is restricted to flex in one plane only. A relatively thin, tapered, elongated protective structure having a relatively sharp, elongated leading edge contiguous with a relatively sharp front edge is rigidly connected to the first cantilevered member and surrounds the second elongated member in a plane orthogonal to the plane of flex.

Abstract: A head mount faithfully follows flexible media perturbations. The head mount consists of a pivoted rigid head support arm controlled by an offset spring having an offset damping and yieldably urging relationship to the rigid arm. The rigid arm acts as a free beam. The arm is pivoted to a record support radially movable with respect to a record disk.
