摘要： A cartridge main body (34) formed by halves (32, 33) for housing a disc (31) having a magnetic member (30) at its centre is provided with a recess (82) in the underside of the upper half (32), the recess being formed by spaced annular lugs (81, 82) which can engage the disc (31) and the magnetic member (32) respectively so that a projection on the disc formed when the magnetic is secured thereto does not contact the disc half (32) and produce debris. Reinforcing projecting ribs (84 a , 84 b ) and reinforcing projections (88, 89) are provided on the halves (32, 33) of the main body (34) in the vicinity of apertures (39, 40) for insertion of a recording/reproducing head of recording/reproducing apparatus and in the vicinity of an adjacent side edge of the cartridge main body (34) along which a shutter (41) can be slid to cover or not to cover the apertures (39, 40). A shutter locking member (47), provided with a portion (60) of flexible material, can pivot on the housing half (33) and is engaged by an engaging part (48) of the shutter (41).

摘要： Costs are reduced by rationalizing the process while maintaining the sliding performance with respect to a optical disk and a disk table and the reliability is improved. A plate 21 having a slidability film 17, which has heat-resistant, non-adhesive characteristics, on one side thereof is used as a material. A chucking plate is formed by subjecting the plate 21 to predetermined press processing from a side at which the slidability film is not formed, and is attached to a cartridge housing 2 such that a slidability-film-applied surface 8d faces a disk 5.

摘要： A disc cartridge having rotatably housed an optical disc (2) is disclosed. The disc cartridge includes a main cartridge body unit (5) having an aperture for the head part (13) for exposing a portion of the optical disc to outside across the inner and outer rims of the disc. In one surface of the main cartridge body unit is formed a center opening (12) into which is intruded a turntable (90) for rotationally driving the optical disc. An inner peripheral surface (81) of the center opening operates as a mounting reference plane along the planar direction when mounting the disc cartridge to a recording and/or reproducing apparatus. The rim of the opening of the one surface of the main cartridge body unit operates as a mounting reference surface (82) along the height-wise direction. The main cartridge body unit has an inserting end side into the recording and/or reproducing apparatus formed as a substantially semicircular arcuate section (7) having, as center, the center of the optical disc housed in the main cartridge body unit.

摘要： A disc cartridge including a disc (D) which is an information recording medium and a case (103) for accommodating the disc. The disc cartridge includes at least one centering spring (130) for preventing deviation of the disc (D), which is provided with a predetermined gap outwardly from the outer circumference of the disc in the case. Thus, a gap in which a disc moves in the disc cartridge is restricted so that the length in which the disc clamp contacts the disc clamp guide can be reduced. Also, the height of the disc clamp is reduced so that the thickness of the cartridge is reduced and miniaturization of the disc cartridge is possible.

摘要翻译： 一种盘盒，包括作为信息记录介质的盘（D）和用于容纳盘的盒（103）。 盘盒包括至少一个用于防止盘（D）偏离的定心弹簧（130），盘（D）在盒中从盘的外圆周向外具有预定间隙。 因此，限制了盘在盘盒中移动的间隙，从而可以减小盘夹与盘夹持导向件接触的长度。 而且，光盘夹的高度减小，使得光盘盒的厚度减小并且可以使光盘盒小型化。
