ABSTRACT:
A compact disk protector for an optical data storage disk includes a thin, transparent sheet having an inside diameter being larger than an inner hole of the disk and the sheet extending within and being bounded by a main region for placement against a first side of the disk, and approximately 24 circumferentially spaced support portions extending radially outwardly from the main region to a distance being greater than a thickness of the disk beyond the disk outside diameter. Each support portion has a bridge width being not greater than 2 percent of the disk outside diameter within a bridge region that is concentric with the inside diameter and extends from the disk outside diameter radially outwardly a distance corresponding to the disk thickness. A retainer holds the support portions folded against a second side of the disk when the main region of the sheet is placed against the first side of the disk, the inside diameter of the sheet being maintained concentric with the disk outside diameter by the bridge portions engaging outside edge portions of the disk, the retainer being a thin, sheet having an inside diameter larger than the inner hole of the disk, the sheet being smaller than the disk and having adhesive applied to one side for contacting the support portions.
