  • Publication number: 20060294530
    Abstract: A disk recording-reproducing apparatus ensures a large transport distance of a tray which moves a disk-shaped recording medium between an ejecting position and a recording-reproducing position while decreasing a dimension in the transport direction. A drive section (47) is built into a tray (13) which can be extracted from and retracted into an external chassis (10) and moves a disk-shaped recording medium between the ejecting position and the recording-reproducing position. A pinion (56) comprises an output end of the drive section (47) and rolls on a rack (24) of a chucking slider (20) to self-propel the tray (13). After the tray (13) completely moves to the recording-reproducing apparatus side, an output from the drive section (47) of the tray (13) is used to move the chucking slider (20) to the ejecting direction of the tray (13). Then, a cam groove (23) provided on the chucking slider (20) is used to raise a base unit (30).

  • Patent number: 7137129
    Abstract: A disk drive apparatus includes a casing having an upper plate; and a tray. The upper plate includes an arm having an attracted member fixed thereto. When the tray moves from a protruding position to a recording-and-playback position, since engagements of the arm and the tray are engaged with each other, the main body of the arm swings, and the attracted member serves as a chucking position facing a chucked portion of the disk-shaped recording medium placed on the tray. When the tray moves from the recording-and-playback position to the protruding position, since the engagement of the arm is detached from the engagement of the tray, the main body of the arm swings, and the attracted member serves as a retracting position retracting above the chucked portion of the disk-shaped recording medium.

  • Patent number: 7017167
    Abstract: A disc type recording and/or reproducing apparatus automatically performs the opening and closing of a shutter provided on a cartridge housing an optical disc in its case, and prevents the above-mentioned opening and closing mechanism from affecting the cartridge after an end of loading. When a DVR cartridge (51) is drawn into a recording and reproducing position by means of a tray (13), a shutter opening and closing mechanism (65) arranged on the side of the apparatus is relatively moved with regard to the cartridge (51). Thereby, shutter plates (100) of the cartridge (51) are opened or closed. Then, after the shutter plates (100) are completely released, the shutter opening and closing mechanism (65) is retracted by means of a cam (85) to be away from the cartridge (51).

  • Patent number: 6964056
    Abstract: Disclosed is a disk recording and reproduction apparatus for recording and/or reproduction of optical disks of multiple different formats impossible to record or reproduce with a single pickup. A disk recording and reproduction apparatus containing a base unit (25) with two separate optical pickups (31) and (32) corresponding to two different format types and installed around the center of a turntable (27) for rotating a disk.

  • Publication number: 20040250267
    Abstract: In a disc cartridge, the shutter opening/closing operation is to be performed reliably. To this end, the distal ends of a first engagement member 75 and a second engagement member 79 provided to a base 66 are pivotally movable in a direction along a lateral surface of a housing 51, in addition to being movable in a direction perpendicular to the lateral surface of the housing 51. The state of engagement of the first engagement member 75 and the second engagement member 79, provided to the base, with a first mating engagement section 110 and with a second mating engagement section 108, provided to an inner rotor 101, facing outwards from one lateral surface of the housing 51, when the base 66 performs relative movement along the lateral surface of the housing 51, may be maintained for prolonged time, while the load applied to the distal ends during engagement and disengagement may be reduced.
