    "3. The disc library storage system according to claim 2, wherein each of the storage cartridge assemblies comprises the fixing column and a plurality of disc storage cartridges rotatably disposed on the fixing column, and two ends of the fixing column are detachably disposed on the upper cover and the lower cover respectively through a corresponding fixing piece.",
    "4. The disc library storage system according to claim 1, wherein the disc library comprises the plurality of disc storage cartridges, the disc transport device comprises a disc grabbing device and a lifting mechanism driving the disc grabbing device to vertically move to a vertical position of a corresponding disc storage cartridge; the disc grabbing device comprises a push lever; when the disc library rotates along a first direction, the push lever pushes the corresponding disc storage cartridge out the disc library.",
    "5. The disc library storage system according to claim 4, wherein a tip of the push lever has a roller; each of the disc storage cartridges has an outer flange; when the disc library rotates along the first direction and the push lever pushed the corresponding disc storage cartridge out the disc library, the push lever contacts the outer flange through the roller.",
    "6. The disc library storage system according to claim 1, wherein the disc library comprises the plurality of disc storage cartridges, the disc transport device comprises an optical positioning device for positioning a position at which the disc storage cartridge is pushed out the disc library; the optical positioning device emits a light spot for detecting a position of an edge contour of the disc storage cartridge to determine whether the disc storage cartridge has reached a positioning point.",
    "7. The disc library storage system according to claim 1, wherein the disc transport device further comprises at least one position adjusting mechanism for adjusting a position of the disc transport device to adjust the position correspondences among the disc transport device, the disc library and the disc drive tower.",
    "8. The disc library storage system according to claim 1, wherein the disc drive tower further comprises at least one position adjusting mechanism for adjusting a position of the disc drive tower to adjust the position correspondences among the disc drive tower, the disc library and the disc transport device.",
    "9. The disc library storage system according to claim 1, further comprising a tray support frame disposed opposite to the disc drive tower, wherein the tray support frame comprises a plurality of support recesses respectively disposed corresponding to positions of trays of the disc drives; when the tray of the disc drive is ejected from the disc drive, a front end of the tray leans on a corresponding support recess.",
    "10. The disc library storage system according to claim 1, wherein the disc drive tower comprises a disc supplement cartridge slidably disposed on a bottom of the disc drive tower.",
    "11. The disc library storage system according to claim 1, wherein the disc drive tower comprises a casing; each of the disc drives is positioned on the casing through a first positioning slot, a second positioning slot, a first positioning rod and a second positioning rod; the first positioning slot and the second positioning slot are disposed at different horizontal planes on one side of the casing; a length of the first positioning slot is different from a length of the second positioning slot; the first positioning rod and the second positioning rod are disposed at different horizontal planes and different vertical planes on one side of the disc drive; the first positioning rod and the second positioning rod are correspondingly disposed in the first positioning slot and the second positioning slot, respectively.",
    "12. The disc library storage system according to claim 1, wherein the interference arm matches with the fixing column through interference fit both when the disc storage cartridge is inside the disc library and when the disc storage cartridge is located at a positioning point out of the disc library.",
    "13. The disc library storage system according to claim 1, wherein before the disc storage cartridge is mounted on the fixing column, an inner side of the interference arm partly overlaps the fixing column.",
    "14. The disc library storage system according to claim 1, wherein when the disc storage cartridge is mounted on the fixing column, the interference arm is pushed outwards by the fixing column to press against and apply an elastic force to the fixing column.",
    "15. The disc library storage system according to claim 1, wherein the disc transport device comprises an optical positioning device for positioning a position at which the disc storage cartridge rotates out of the disc library.",
    "16. The disc library storage system according to claim 14, wherein the optical positioning device emits a light spot for detecting a position of an edge contour of the disc storage cartridge to determine whether the disc storage cartridge has reached a positioning point.",
    "17. The disc library storage system according to claim 1, wherein the disc library further comprises an upper cover and a lower cover, and two ends of the fixing column are detachably disposed on the upper cover and the lower cover respectively."

  "description_excerpt": "This application claims the benefits of U.S. provisional application Ser. No. 62/581,769, filed Nov. 5, 2017 and People's Republic of China application Serial No. 201810264583.7, filed Mar. 28, 2018, the subject matters of which are incorporated herein by reference.\n\nThe invention relates in general to a database storage system, and more particularly to a disc library storage system using discs as a storage medium for storing a large volume of data.\n\nThe disc drive is installed in a personal computer to read data from the disc or write data to the disc, and is normally used for storing a small volume of data. However, along with the development of big data, the database storage system is provided to store a large volume of data. Therefore, it has become a prominent task to the industries to use discs as a storage medium and combine discs and disc drives to form a disc library storage system capable of storing a large volume of data to increase the storage capacity of the database storage system.\n\nThe invention is related to a disc library storage system using discs as a storage medium for storing a large volume of data to increase the capacity of data storage.\n\nAccording to one embodiment of the present invention, a disc library storage system including a disc library, a disc drive tower and a disc transport device is provided. The disc library is used for placing multiple discs. The disc drive tower includes multiple disc drives for reading data from the discs or writing data into the discs.",
