Abstract: An improved reinforcement member for a central aperture in a flexible recording disk and a method for forming the same. The improved reinforcement comprises an integral, annular-shaped ring formed on one or both sides of the flexible recording disk about the central aperture thereof. This improved reinforcement is formed by transfer printing a liquid image of the reinforcement member onto a side surface of the flexible recording disk and then subsequently solidifying that liquid image. The liquid image to be transfer printed onto the flexible recording disk is first established by filling a metering reservoir shaped to be an image of the reinforcement member with a solidifying liquid. A terminal end of compliant rubber tampon is then first contacted to the reservoir thereby picking up the liquid image which is then contacted to the surface of the flexible disk to be deposited there.
