This paper or topic gives the details of the “THREE DIMENSIONAL DATA STORAGE”. There are two types of 3-D storage technology
1) Holographic Storage Technology
2) Multi –layer Storage Technology
Both technologies are currently in developing phase. In the Holographic Storage technology there is a description about it which can show how it is superior from the other recent technologies, such as CD/DVD. Paper also includes the mechanism for reading and writing the data in the storage media and also the requirement for the storage material that used for storage the data. Also include the description of the some of the institutes. While in the Fluorescent material multi-layer technology, paper include that how the production of the storage media is done in this storage technology and the current development status of the storage technology. Also include the mechanism for read/write head.
