摘要： A disc cartridge capable of preventing entering of dust into a casing and ensuring a stable and positive operation without damaging a disc while satisfactorily exhibiting a cleaning effect and keeping proper contact between a recording head and the disc. A casing is provided thereon with a slide area which is formed by a slide area defining section of the casing. The slide area is formed with at least one head inserting hole. The slide area defining section is provided on an inner surface thereof with at least one thick-walled portion in a manner to extend along a whole periphery of a portion of the head inserting hole overlapping a sheet-like liner and inwardly project from the inner surface of the casing, so that the liner may be pressed against the disc at a force of a constant level over a wide area of the disc and block a communication between an exterior of the cartridge and its interior through the head inserting hole.

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.
