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.
The optical method benefits those with large storage requirements

Single layer, single sided Blue-ray disc
The best format for optical media largely depends on the intended use, but generally, Blu-ray discs are considered superior for high-definition video storage due to their higher capacity and better data compression compared to DVDs and CDs. For archival purposes, M-DISC technology offers longevity and durability, making it ideal for long-term data storage. Ultimately, the choice should align with specific needs such as storage capacity, compatibility, and longevity.
no,harddisk is not an optical storage
Optical use a laser to read and write data .Optical disks have very large storage capacity but they are not fast as harddisk .There are major types of optical disk 1.CD-Rom 2 Worm 3.Eraser Advantage's optical disks has a very high storing capacity ,inexpensive has along life of at least 25 years .
A compact disc is a type of optical disc. "Optical disc" is an umbrella term for any type of storage media which uses optical technology (as opposed to magnetic) for data storage. This includes but is not limited to DVDs, CDs, H-DVD, blu-ray, laser discs CDRW's, and DVDRW's
