ABSTRACT:
A disc cartridge of the present invention has an arrangement in which a disc cover is provided so as to cover one side of a disc in a disc shape having a recording layer for recording/reproducing information. This arrangement protects a surface for recording/reproducing from being damaged, being attached by dust, or being dirty. Meanwhile, this arrangement gives a significantly thinner thickness to the disc cartridge.
