Advantages of Optical Storage Devices. Optical Storage Devices-DVD
DVDs are amongst the most common methods of copying and backing up data at home.
A DVD is similar to a CD in that it is an optical device and that a laser is used to store the data and read the data.

Optical storage media stores data on a disc as a number of data dots that can be read using light (usually a laser beam). border: solid 1px #AAE; Optical storage does not provide enough data storage in comparison to other storage technologies. Compared to other types of storage such as magnetic hard drives, the disks used in optical storage can be quite inexpensive and lightweight, making them easy to ship and transport.They also have the advantage of being removable, unlike disks in typical hard drive, and they're able to store much more information than previous types of removable media such as floppy disks.
