FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -An optical disk drive uses a laser beam to read the data from the disk as it is spinning.

Detailed explanation-2: -Optical storage is any storage method that uses a laser to store and retrieve data from optical media.

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: -A DVD drive uses a laser to read data that have been encoded onto a DVD. Because the DVD laser emits red light at shorter wavelengths than those used for other optical discs, such as CDs, a DVD can achieve greater storage density.

Detailed explanation-5: -Optical data storage is the use of light to write and read information to and from a memory device. Storage can be achieved by using lasers to pattern a surface, such as on a compact disc, or altering the physical properties of a small volume inside a light sensitive material.
