Similarly, when optical disc cartridges are fixed in multiple fixing devices in the first frame 301, the adjacent set number of optical disc cartridges can form an optical disc bin, and the adjacent set number of optical disc cartridges are inserted or removed from the optical disc library using the optical disc bin.

[0059] By assembling a plurality of adjacent optical disc cartridges into an optical disc magazine, the efficiency of inserting or removing optical disc cartridges from an optical disc library is improved.
