Abstract: 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.

Abstract: A disc cartridge includes a shutter unit having an outer shutter and inner shutters to open and shut apertures on the disc cartridge. The outer shutter opens one of the inner shutters corresponding to a side of the disc cartridge being accessed by a pickup. Accordingly, the overall area of the apertures exposed to the exterior during information recording and reproducing operations is reduced. Accordingly, dust is less likely to enter into the disc cartridge.

Abstract translation: 盘盒包括具有外挡板和内百叶窗以打开和关闭盘盒上的孔的快门单元。 外部快门打开与由拾取器接近的盘盒的一侧对应的内部快门之一。 因此，减少了在信息记录和再现操作期间暴露于外部的孔的总面积。 因此，灰尘不太可能进入盘盒。

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.

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.

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.
