One of the main advantages of 3D optical storage is capacity; it is possible to store far additional data visually than can be stored all the way through its chief alternative-magnetic storage.

The 3D disc contains many coating of information, each at the different depth in the media, And it consist like a DVD spiral track. Data recording in a 3D optical storage intermediate need an alternation that get place in the middle leading excitation. In order to record information on the disc a laser is carry out to a focus at a exacting depth in the media that communicate to a exacting information layer.

Multicast is simply known as that a single sender is communicated with the multiple receivers on network.
