Detailed explanation-1: -optical storage, electronic storage medium that uses low-power laser beams to record and retrieve digital (binary) data. In optical-storage technology, a laser beam encodes digital data onto an optical, or laser, disk in the form of tiny pits arranged in a spiral track on the disk’s surface.
Detailed explanation-2: -Optical disks rely on a red or blue laser to record and read data. Most of today’s optical disks are flat, circular and 12 centimeters in diameter. Data is stored on the disk in the form of microscopic data pits and lands. The pits are etched into a reflective layer of recording material.
Detailed explanation-3: -Optical storage is any storage type in which data is written and read with a laser. Typically, data is written to optical media such as compact discs (CDs) and digital versatile discs (DVDs).
Detailed explanation-4: -The optical disc makes use of laser technology: digital data are recorded by burning a series of microscopic holes, or pits, with a laser beam into thin metallic film on the surface of a 43/4-inch (12-centimetre) plastic…
Detailed explanation-5: -Alternatively called a disc drive, optical media, optical storage, and Optical disc drive, an optical disc is any media read using a laser assembly. The most common types of optical media are Blu-ray, CDs, and DVDs.
