摘要： A disk cartridge having a cartridge body (5) for rotatably receiving an optical disk (2) and having an opening (13) for a head, where the opening enables portion, from its inner to outer peripheries, of the optical disk (2) to face outward, a shutter member (15) movably supported by the cartridge body (5) and opening and closing the opening (13), and a bidirectional urging mechanism (38) for selectively urging the shutter member (15) either to the position where the opening (13) is closed or to the position where the opening (13) is opened. The bidirectional urging mechanism (38) urges the shutter member (15) either to the direction to close the opening (13) or to the direction to open the opening (13) depending on the position of the shutter member (15) relative to the opening (13).

摘要： A disc recorder/reproducer (101) comprising a chassis (103) supporting a holder (102) containing a disc cartridge rotatably, an eject lever (105) provided on the chassis movably in the inserting/drawing direction of the disc cartridge and movably in the approaching/receding direction to/from the chassis and being pushed by the disc cartridge (1) inserted into the holder to rotate, and a cartridge falling preventive means (221) for preventing the disc cartridge (1) ejected by the eject lever (105) from falling off from the cartridge holder (102). The falling preventive means (221) is provided on one side face (102b) of the holder and comprises a leaf spring for imparting a brake force to the disc cartridge by sliding on one side face (3b) thereof at the time of discharging the cartridge. Consequently, the disc cartridge can be prevented from projecting from the cartridge holder and falling.
