Disc cartridge and casing therefor

摘要

A disc cartridge and a casing therefore capable of carrying out insertion and removal of a disc with respect to the casing without separating a shutter from the disc cartridge and adversely affecting the disc, with simple operation. The casing includes a casing body constituted by an upper cover member and a lower cover member joined together to form an inner space therein which is adapted to rotatably receive therein a disc having a non-recording section formed at its outer periphery and be separable at rear ends thereof from each other. The casing also includes a pair of guides arranged on both side of a rear portion of an interior of the casing body so as to be opposite to each other. The guides permit insertion and removal of the disc with respect to the casing body to be safely accomplished along the guides through the opened rear end of the casing. The disc cartridge uses such a casing.
