Therefore, it is the current situation that they are transported in such a strict packaging form. For this reason, in the packing work process of the disks 1, a non-woven bag 2 is prepared for each disk, and the packing work process such as packing with the plastic bag 3 and temporary packing with the cardboard box 6 is complicated. As much as possible, the number of packing components such as the use of cushioning materials 7 and 10 and the sealing tape 8 increases, and from the packing work from the factory shipment to the unpacking work at the time of shipment due to the complexity of parts management. There was a drawback that the total logistics cost of In addition, due to the reliability of the signal surface of the disc, during packing and unpacking, fine foam scraps generated from Styrofoam adhere to the signal surface, and there are multiple through holes in each of the upper and lower housings. Since it was provided, it was necessary to completely protect paper dust generated from the corrugated cardboard from adhering to the signal surface of the disc, but this has not been completely solved in the past. Especially for high-density discs using compression technology, protection of the signal surface is indispensable, and without this, complete reproduction of intended information is undesired.
