[0087] As a usage mode, the five-dimensional optical storage device 100 can adopt the following steps to implement the placement of the storage medium 90, that is, to move the storage medium 90 from the storage device 30 to the drum device 20.

[0088] The drum body 21 of the drum device 20 is rotated so that the receiving groove 212 in the placement area 211 of the drum body 21 which is in an empty state is at the top.

[0089] The storage device 30 moves the cabin 31 so that the storage medium 90 to be placed is aligned with the uppermost receiving groove 212 of the drum body 21 .

[0090] The second pushing member 33 pushes the storage medium 90 , and the storage medium 90 moves from the chamber 31 to the receiving groove 212 at the top of the drum body 21 .

[0091] The storage medium 90 is inserted.

[0092] The steps for removing the storage medium 90 are briefly described as follows.

[0093] The drum body 21 of the drum device 20 is rotated so that the storage medium 90 to be removed from the drum body 21 is located at the top.

[0094] The storage device 30 moves the cabin body 31 so that the cabin body 31 in an empty state is aligned with the uppermost receiving groove 212 of the drum body 21 .

[0095] The first pushing member 32 pushes the storage medium 90 , and the storage medium 90 moves from the rotating drum 21 to the chamber 31 .

[0096] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
