An optical disc cartridge for storing an optical disc. The cover of the optical
disc cartridge absorbs or filters ambient light which may damage information stored
on the disc after prolonged exposure to the ambient light. Preferably, the disc
cartridge cover allows some visible light to pass in order to allow a user to read
label information on the disc. The color of the cover may be transparent to visible
light, allow only specific visible wavelengths of light to pass, or be opaque,
as long as the amount of ambient light reaching the disc stored within the disc
cartridge is reduced. The disc cover may be made of a single layer or include a
base layer with one or more thin films thereon.
