Detailed explanation-1: -optical storage, electronic storage medium that uses low-power laser beams to record and retrieve digital (binary) data.
Detailed explanation-2: -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-3: -An optical disk drive uses a laser beam to read the data from the disk as it is spinning. It distinguishes between the pits and lands based on how the light reflects off the recording material.
Detailed explanation-4: -Six categories of optical media are available to meet most storage requirements: CD-ROM, DVD-ROM, DVD-RAM, recordable media, write-once read-many (WORM) optical cartridges, and erasable optical cartridges.
Detailed explanation-5: -Conventional optical technologies such as CD, DVD and magneto-optical (MO) drives write data using red lasers.
