Optical Media

Optical media refers to storage devices that use laser technology to read and write data on discs like CDs, DVDs, and Blu-ray discs. Data is stored in tiny pits and lands on the disc's surface, and a laser reads these variations to retrieve information such as music, videos, or software. This method provides a portable, durable way to store large amounts of data, with different disc types offering varying capacities and quality. Optical media is widely used for distribution and backup due to its reliability and ease of use.
