ABSTRACT:
A disc cartridge capable of preventing a recording surface section of a disc from being contacted by a casing and placing the disc at a proper position in the casing without damaging and polluting, to thereby ensure the safe and smooth operation of the disc in the casing. The disc cartridge includes a pair of disc receivers each of which is formed therein with a recess for receiving a peripheral portion of the disc. The recess has an end surface contacting an outer periphery of the disc, which is formed into a substantially sideways V-shape of which an apex is positioned at substantially a center of the end surface to position the outer periphery of the disc at the center of the end surface.
