Abstract

Abstract A thin, flat, polymer, scratch resistant, user applied disc protector with self-adhesive backing which affixes to the top of a compact disc to help eliminate possible damage from impact which would render the disc in a semi-unplayable or unplayable condition. This extra layer of user applied protection is prefabricated to proper size to adhesively secure to various optical mediums with a self-adhesive layer by an application method of installation on the top, protective side of the disc. Adhesive allows for permanent placement on the disc for convenience without hindering operation of the disc and without hindering readability of the context of the information lettering. This disc protector can include a removable peel-away backing.
