Abstract: The CD storage device includes a central positioning post being vacuum shaped of plastic with suitable elasticity, a plurality of solid top surfaces provided on the top of the central positioning post, the central positioning post is provided with more than one contractible-by-pressing gap to divide the central positioning post into a plurality of hollow separated blocks. Thereby an improved CD storage device is formed; the device is particularly suitable for vacuum forming with low cost to make positioning of the central positioning post for a CD, and is able to allow taking the CD off the CD storage device under the condition of applying a light force and scrape-proofing.
