摘要： An optical disk 100 is provided with a hub 3 at the central portion of a substratel. A relationship Y/X≧0.015, preferably Y/X≧0.05 is satisfied where X is the projected area of the substrate 1 and Y is a contact area between the hub 3 and the substrate 1. As result, no slippage occurs between the hub 3 and the substrate 1 even when they are rotated at high speed than conventional. With this higher rotational speed, the data transfer rate is improved, and irregular rotation and the camming are suppressed, thereby reducing tracking errors and write/read errors.
摘要翻译：光盘100在基底的中心部分设置有轮毂3。满足关系Y / X> = 0.015，优选为Y / X> = 0.05，其中X是基板1的投影面积，Y是毂3和基板1之间的接触面积。结果，即使在轮毂3和基板1之间高速旋转时也不会发生滑动。利用这种较高的转速，数据传送速率得到改善，并且不规则旋转和凸轮被抑制，从而减少跟踪误差和写/读错误。

摘要： A cartridge includes upper and lower half segments butting against each other and containing a disk, a shutter provided on one side of the cartridge half segments for exposing or alternatively enclosing the disk, and a torsion spring attached to the shutter for biasing the shutter in a closing direction. An insertion opening is formed in a side portion of the cartridge for permitting insertion of the torsion spring therethrough from outside, and a protective wall is provided upright between the insertion opening and the disk to define a space by the wall and the upper half segment. The space is so sized as to permit the torsion spring to pass therethrough while leaving a small clearance, with legs thereof directed laterally.

摘要： There is provided a tape cartridge comprising a tape receiving member formed near a tape running path in the tape cartridge for receiving a tape, and a tape pushing member arranged to face the tape receiving member through the tape, the tape pushing member being arranged to move between a tape pinching position in which the tape is pinched between the tape receiving member and the tape pushing member, and a cancellation position in which the tape pushing member moves away from the tape. Accordingly, when the tape pushing member is positioned at the tape pinching position, the tape cartridge can prevent the tape from protruding from the front surface of the tape cartridge.
