  • Patent number: 6415918
    Abstract: A disc holder having a rigid central core for projecting through the central aperture of an optical disc in order to hold the optical disc in place. The disc holder includes, in addition to the rigid central core, a base, several support arms that extend radially inwardly from the base to support the central core in spaced relation from the base, and securing means for releasably securing the rigid central core within the central aperture of the optical disc. The securing means includes locking fingers mounted on the central core. The locking fingers are biased outwardly against the edge of the central aperture of the disc when the disc is held by the disc holder. The locking fingers are moveable radially inward to fit within the central aperture of the disc, thereby allowing the disc to move over the locking fingers so that the disc can be put on or taken off the disc holder.
