Retaining structure, disk retaining structure and disk storage structure with double-face carrier function

A disk storage structure with double-face carrier function, comprising:

• a disk storage box having a top cover unit and a bottom cover unit corresponding to the top cover unit, wherein one end of the top cover unit and one end of the bottom cover unit are connected with each other in order to selectively open or close the disk storage box;
• a carrier unit having a carrier body received in the disk storage box and a through hole passing through the carrier body;
• an elastic unit having a plurality of elastic arms extended from an inner surface of the through hole;
• and
• a retaining unit having a plurality of retaining elements passing through the through hole and disposed in the disk storage box, wherein each retaining element has a retaining portion connected to at least two of the elastic arms and extended above and under the through hole, a pressing portion extended inwards from one end of the retaining portion and at least one protrusion portion disposed on an outer surface of the retaining portion and adjacent to the pressing portion, and the pressing portions above the through hole are arranged alternately and the pressing portions under the through hole are arranged alternately.
