摘要： A cartridge for a disk-shaped storage medium, wherein the cartridge has partition walls within the cartridge for separating the storage medium from other portions of the cartridge, thereby protecting the storage medium from damage due to debris particles. The partition walls are formed by ribs which protrude from the interior surfaces of each half of the cartridge. The ribs do not meet but rather define a small gap between them. The top of one rib has a V-shaped protrusion (taken perpendicular to the length of the rib) while the top of the other rib has a complementary V-shaped groove. Elongate debris particles are blocked from passage into the compartment containing the storage medium due to the tortuous path defined by the gap.

摘要： An optical data storage disc comprising a disc-shaped substrate and a centrally-located magnetizable hub. The disc has a central bore configured to receive a drive pin from an optical disc drive. The substrate has a recessed annular portion adjacent its center bore. The hub is provided within the recessed portion of the substrate. The central bore of the disc may be defined by the central bore of the hub alone, so that the diameter of the hub's bore is less than that of the substrate. In the alternative, the central bore of the disc may be defined in part by the inner bores of both the substrate and the hub, in which case those inner bores are of equal diameter. In either case, the thickness of the disc when measured at its inner portion, i.e., in the area of the hub and recessed portion, is equal to the thickness of the substrate at the periphery thereof. By reducing the thickness of the hub area to that of the substrate itself, the number of discs that can be stored together in a fixed space can be increased, thereby increasing the potential storage capacity of an optical disc jukebox or magazine system.

摘要翻译： 一种光学数据存储盘，包括盘状基板和位于中心的可磁化轮毂。 盘具有被配置为从光盘驱动器接收驱动销的中心孔。 衬底具有邻近其中心孔的凹入的环形部分。 毂设置在基板的凹部内。 盘的中心孔可以由单独的毂的中心孔限定，使得毂的孔的直径小于衬底的直径。 在替代方案中，盘的中心孔可以部分地由衬底和轮毂的内孔限定，在这种情况下，这些内孔的直径相等。 在任一情况下，当在其内部部分，即在毂部和凹部的区域中测量时，盘的厚度等于其周边处的基板的厚度。 通过将集线器面积的厚度减小到衬底本身的厚度，可以增加可以一起存储在固定空间中的盘的数量，从而增加了光盘自动存储器或盒式系统的潜在存储容量。

摘要： A disk cartridge for a rotatable recording disk includes a slidable shutter for providing access to the recording disk through the disk cartridge. A unique mounting for a return spring for the shutter allows the return spring to be of a maximum length which allows increased control of the forces generated by the return spring. The disk cartridge is further provided with a locking mechanism for preventing movement of the recording disk within the disk cartridge during storage.
