Optical backing storage refers to data storage technology that uses optical discs, such as CDs, DVDs, and Blu-ray discs, to store and retrieve digital information. These discs are read and written using laser technology, allowing for high-capacity storage and durability. Optical backing storage is often used for archival purposes, software distribution, and media storage due to its resistance to electromagnetic interference and long shelf life. However, it is generally slower than other storage methods like hard drives or solid-state drives.
