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 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 high density disc having a data area which is set such that compatibility is secured in the same drive while maintaining a superior recording and/or reproducing feature. The high density disc has a center hole, a clamping area, a data area where user data is recorded, a lead-in area located at the inner side of the data area, and a lead-out area located at the outer side of the data area. In the high density disc in which the diameter of the center hole is 10 mm or more, the inner diameter of the clamping area is characteristically within a range of 20-26 mm. Also, the inner diameter of the data area is characteristically within a range of 35-40 mm. Therefore, while a conventional disc drive is still used, the size of the high density disc decreases and a recording capacity can be increased.
