What is an Optical Storage System?
As compared to magnetic memory, optical memory is a relatively new secondary storage medium. It has provided to be a promising random medium for high-capacity secondary storage, as it can store large amounts of text of data in limited space. An optical-disk storage system consists of a rotating disk, which is coated. With a thin metal or any other material that is highly reflective. laser beam technology is used for recording/reading data on a disk. Due to this, optical disks are also known as laser disks or optical laser disks.
The optical memory can be classified into three categories:
- CD (Compact Disk)
- DVD (Digital Video Disk)
- Blu-Ray Disk
Optical Storage Systems
THe Optical memory is an electronic storage medium that uses a laser beam to store and retrieve digital (binary) data. In optical storage technology, a laser beam encodes digital data on an optical disc or laser disc in the form of tiny pits arranged in a spiral pattern on the surface of the disc. Digital Versatile Disk (DVD), Compact Disk (CD) and Blu-Ray Disk are the examples of optical storage device.
