    Abstract: The invention provides a disk cartridge having an optical disk (2) stored therein. The disk cartridge comprises a cartridge main body (5) formed with a head opening (13) for rotatably storing an optical disk and causing a part of the optical disk to face outward over the inner and outer peripheries, and a shutter member (15) movably attached to the cartridge main body and adapted to open/close the head opening (13). A region in the surface of the cartridge main body on which the shutter member slides and which is disposed across the head opening from a region in which the shutter member moves is formed with a bottomed recess (31) continuous with the head opening to allow a part of the head on the recording and/or reproducing device to enter the bottomed recess (31).

    Abstract: 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).

    Abstract: Disclosed is a disc cartridge in which is housed an optical disc (2). The disc cartridge includes a main cartridge body unit (5), rotatably housing an optical disc, and having an aperture for a head part (13) for exposing a part of the optical disc to outside across the inner and outer rims of the optical disc, and a shutter unit (15) mounted for movement to this main cartridge body unit for opening/closing the aperture for the head part (13). A recess (31) into which is introduced a portion of a head part of the recording and/or reproducing apparatus is formed in continuation to the aperture for the head part in a surface of the main cartridge body unit on which slides a shutter unit in an area opposite to the area of movement of the shutter unit with the aperture for the head part in-between.

    Abstract: A disk drive unit includes a disk stabilizer block supporting a reading and/or writing head. The disk stabilizer block is formed a surface to sealingly contact with a mating surface of the disk. At least one void is formed on the disk stabilizer block for defining a chamber around the reading and/or writing head, in which Bernoulli drawing force is generated for drawing a flexible storage medium disk. The void reduces contact area between the stabilizer block and the disk for avoiding influence of tolerance in production of the stabilizer block and influence of waving of the disk during rotation.
