ABSTRACT:
A support for a stretched recording film and method of attaching the film to the support. The support includes a flat disk-shaped base, an annular upstanding rim which terminates in a reference surface, an annular radially extending bonding lip which includes a bonding surface inclined with respect to the plane of the base, and a groove separating the reference surface and the bonding surface. The method of attaching the film to the support includes deflecting the center of the base to decrease the diameter of the bonding surface, bonding the film to the bonding surface, and ceasing to deflect the base so that the diameter of the bonding surface increases to induce tension in the film. A second protective layer of film may be simultaneously stretched over and bonded to the first layer of film.
