摘要： 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.

摘要： 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.
摘要翻译：磁盘盒包括一个形成在其上的开口的下壳体，上壳体安装在下壳体上以能够在枢转时打开和关闭，以容纳其间的盘;安装在下壳体上以便滑动的闸板并且打开和关闭所述开孔;紧盖件，其具有安装在所述闸门处以能够滑动的倾斜表面，当所述闸门关闭时，与所述盘的内周设置的非信息区域紧密接触; 从快门打开时设置在盘的内周的非信息区域。因此，当快门关闭时，防止灰尘的引入，使得盘的信息区域被污染的可能性降低。此外，由于盘被固定在上壳体和下壳体之间，而在托盘的作用下，可以降低噪声和损坏。

摘要： 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.
摘要翻译：磁盘盒包括容纳盘的壳体，安装在壳体上以能够被打开和关闭并且具有形成在其上的孔以敞开到盖的外部的盖，在壳体下方安装的盘，能够移动以打开和关闭形成在壳体上的开口，以及安装在盖上的夹紧构件以密封孔以夹紧盘。因此，由于夹持构件阻挡连接到盖的外部的盖的孔，因此减少了灰尘进入盘盒的可能性。此外，由于不需要将夹紧构件安装在盘驱动器上，因此可以使盘驱动器变得简单而纤细。

摘要： 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.

摘要： A disk cartridge includes a case which receives a disk thereon, a cover which is installed on the case and includes an opening, and a shutter which is movably installed in the case, in a lower direction of the disk, to open and close an aperture formed on the case. The disk cartridge has guide holes formed on the case along a trace of the shutter, and support members formed on the shutter. The support members are guided along the guide holes while having ends thereof interfering with peripherals of the guide holes. Therefore, since the peripherals of the guide holes interfere with the ends of the support members, the shutter is prevented from being deformed even where an external force is applied to the shutter through the aperture, in a closed state of the shutter.

摘要： 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. Also, since an edge portion of the outer circumferential side of the disk closely contacts a sealing member disposed around the second hole of the cover in a state that the shutter is shut, a gap through which dust can intrude is blocked, so that contamination of the recording surface can be reduced.
摘要翻译：磁盘盒包括容纳盘并具有第一孔的壳体，安装在壳体处的盖，并且具有通向盖的外部开口的第二孔;安装成能够相对于设置在壳体下方的壳体移动的挡板盘，以打开/关闭形成在壳体上的第一孔，以及多个突出部分，设置在快门处，以支撑设置在盘的外圆周侧的非信息区域，并具有以预定角度倾斜的倾斜表面。当快门打开时，盘沿倾斜表面下降。当快门关闭时，盘沿着倾斜表面上升，以紧密接触设置在盖的第二孔周围的盖的一部分。因此，由于快门仅接触盘的非信息区域，因此在打开/关闭第一孔的操作期间可以安全地防止盘的信息区域被损坏。此外，由于盘的外周侧的边缘部分在快门关闭的状态下与设置在盖的第二孔周围的密封构件紧密接触，所以可以阻挡灰尘可以侵入的间隙，使得污染可以减小记录表面。

摘要： 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.
