ABSTRACT:
A magnetic recording device employing one or more thin circular foil members which are secured to a supporting member on at least the outer edges of the foil members. In one embodiment, the foil members have central openings therein, with the central opening in one foil member being larger than the opening in the other foil member. A clamping and spacing member is secured to the foil member having the smaller opening and extends through the larger opening in the other foil member to both provide a means for transmitting rotational force to the structure and to provide for spacing between the structure and an adjacent structure in a recording assembly.
In an alternate embodiment, one of the foil members has a central opening while the other does not, and rotational force is transmitted through the foil without the central opening. As additional alternatives, the foils may have central openings of equal sizes and be secured to support members either at their outer edges or at both their inner and outer edges.
