    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： 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 has a reflection portion to identify a kind of a disk in the disk cartridge. A disk drive apparatus has an optical detector to identify the kind of the disk by irradiating a beam to the reflection portion and detecting the reflected beam. The disk cartridge and the disk drive apparatus provide identification marks for identifying the kind of the disk by varying the angle and amount of a beam reflected from the reflection portions on the disk cartridge. Therefore, the kind of a disk and the type of a disk format are identified as well as the storage capacity of the disk.

    摘要： A disk cartridge includes a case which contains a disk, and a shutter which opens/closes at least one opening formed in the case. The shutter is configured to be foldable around upper and lower surfaces of the case, and slides on the upper and lower surfaces of the case to open/close the opening. Since the shutter opens/closes the opening while being folded around the upper and lower surfaces of the case, a movable distance of the shutter for opening/closing the opening can be fully accommodated even though the size of the disk cartridge is reduced. In addition, applying the configuration of the shutter to a double-sided disk cartridge prevents an inflow of dust from entering into the double-sided disk cartridge since the shutter closes an opening, which is not in use, during a recording/reproducing operation.

    摘要： 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/reproducing feature, is disclosed.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.
