    摘要： A disc cartridge having a disc-shaped recording medium, such as an optical disc or a magneto-optical disc, rotatably housed within a main cartridge body. The disc cartridge has a main cartridge body made up of an upper cartridge half and a lower cartridge half, and a disc-shaped recording medium rotatably accommodated within the main cartridge body. A recording and/or reproducing aperture is formed in at least one of major surfaces of the main cartridge body. A shutter is mounted for movement along a sidewall section of the main cartridge body between a position closing the aperture and a position closing the aperture. There is provided an inclined portion in the aperture inclined with respect to the inserting direction of the disc cartridge.

    摘要： A tape cassette has a plurality of spaced apart, elongated bearing surface portions elevated relative to an internal surface of a cassette case and on which a reel lock member is adapted to slide. Accordingly, the sliding movement of the reel lock member is prevented from being hindered by a burr generated at the periphery of a hole formed through the internal surface or by a burr-like projection generated at the periphery of an indentation formed by contact of an ejector pin with the internal surface upon molding of the cassette case. As a result, the locking and unlocking operations of the reel lock member with respect to a tape reel can be reliably effected.
