  • Patent number: 8205220
    Abstract: An optical disc drive to prevent entry of dust through a front side of a tray and includes a housing including a first opening, a shielding member disposed to shield the first opening at a distance from a front side of the housing, and including a second opening, and a tray inserted in the first and the second openings to shield the second opening and loaded into and unloaded from the housing. Thus, since sponge or padding is not dedicatedly used, cost can be saved. In addition, since the manufacturing process is simplified, productivity can be improved.

  • Patent number: 7480922
    Abstract: A disk drive including a tray and an opener. The tray includes a disk cartridge mounted thereon and is loaded into and unloaded from a main body. The opener is installed in the main body and elastically contacts a guide formed on the tray. The opener includes a second gear and a first protrusion. The second gear rotates a rotating wheel when in contact with a first gear. The first protrusion formed on a first end of the second gear temporarily rotates the rotating wheel so that the first and second gears can mesh. The guide has a first cam that moves the opener such that the first protrusion does not interfere with the latch when the tray is loaded/unloaded.

  • Patent number: 7263706
    Abstract: A disk cartridge includes a case accommodating a disk, a cover installed at the case to be capable of being open and shut and having a hole formed thereon to be open to an outside of the cover, a shutter installed under the disk in the case to be capable of moving to open and shut an opening formed on the case, and a clamping member installed at the cover to seal the hole to clamp the disk. Thus, since the clamping member blocks the hole of the cover connected to the outside of the cover, possibility of intrusion of dust into the disk cartridge is reduced. Also, since there is no need to install the clamping member at the disk drive, the disk drive can be made simplified and slim.

  • Patent number: 7237249
    Abstract: A disk drive including a tray on which a disk cartridge is mounted and is loaded into and unloaded from a main body; a guide formed on the tray; and an opening and closing member installed to be elastically connected to the guide. The opening and closing member has a second gear that rotates a rotating wheel by meshing with a first gear; and a first protrusion formed on one end of a second gear and to temporarily rotate the rotating wheel so that the first and second gears can mesh. The guide pushes the first protrusion during loading/unloading of the tray so that the first protrusion and the latch do not come in contact with each other.

  • Patent number: 7197757
    Abstract: A disk cartridge includes a case accommodating a disk and having a first hole, a cover installed at the case and having a second hole open to an outside of the cover, a shutter installed to be capable of moving with respect to the case disposed under the disk to open/shut the first hole formed on the case, and a plurality of protruding portions provided at the shutter to support a non information area provided at an outer circumferential side of the disk and having inclined surfaces inclined at a predetermined angle. When the shutter is opened, the disk descends along the inclined surfaces. When the shutter is shut, the disk ascends along the inclined surfaces to closely contact a portion of the cover disposed around the second hole of the cover. Thus, since the shutter contacts only a non-information area of the disk, an information area of the disk can be safely kept from being damaged during an operation of opening/shutting the first hole.

  • Publication number: 20060282841
    Abstract: A disc recording/reproducing apparatus including a main frame; a tray, mounted to reciprocate on the main frame, having a disc loading part at an upper surface thereof to mount a disc cartridge or a bare disc; a shutter opening/closing unit mounted to the main frame to expose and cover an opening of the disc cartridge according to the reciprocation of the tray; and a cam unit to guide an opening/closing operation part toward the disc loading part when the disc cartridge is loaded on the tray, and to release the guide of the opening/closing operation when the bare disc is loaded on the tray. Alternatively, the disc recording/reproducing apparatus may include a shifting unit to move the opening/closing operation unit toward the disc loading part when the disc cartridge is loaded on the tray, and to separate the opening/closing unit from the disc loading unit when the bare disc is loaded on the tray.

  • Patent number: 7146625
    Abstract: A disc cartridge includes a case accommodating a disc and having an aperture hole formed on a first surface of the case so that a recording/reproducing apparatus access a recording surface of the disc, and an open hole formed on a second surface to be open to an outside of the case, a shutter opening/shutting the aperture hole and installed in the case, a disc holder installed at a side defining the open hole to move up and down and covering a gap between an outer circumference of the disc and an inner surface of the side defining the open hole when the disc holder descends, and a shutter driving mechanism moving the shutter so that the aperture hole is open/shut. Thus, a passage through which dust is introduced toward an information area of the disc, and a gap formed at an outer circumference are blocked by the disc holder so that a possibility of contamination by dust can be reduced.

  • Patent number: 7143427
    Abstract: A disk cartridge includes a case to accommodate a disk, and a shutter installed in the case to move under the disk, and to selectively open/shut an opening hole formed in the case. The disk cartridge includes a support portion to protrude from the shutter to support a non-information area of the disk. Thus, since the shutter contacts only the non-information area of the disk, the information area of the disk is protected during an operation of the shutter to open and shut the opening hole.

  • Patent number: 7124423
    Abstract: A disk cartridge includes a lower case having an opening formed thereon, an upper case installed at the lower case to be capable of being open and shut while pivoting, to accommodate a disk therebetween, a shutter installed at the lower case to be capable of sliding and opening and shutting the opening hole, a close covering member having an inclined surface installed at the shutter to be capable of sliding, closely contacting a non-information area disposed at an inner circumference of the disk when the shutter is closed, and being separated from the non-information area disposed at the inner circumference of the disk when the shutter is open. Thus, when the shutter is closed, introduction of dust is prevented so that the possibility of the information area of the disk being contaminated is lowered. Also, since the disk is fixed between the upper and lower cases, while the disk is carried, noise and damage can be reduced.
