Optical media refers to storage devices that use laser technology to read and write data. Common examples include CDs, DVDs, and Blu-ray discs. These discs store information in the form of tiny pits and lands on their surface, which a laser beam can detect. Optical media is widely used for distributing music, movies, and software. They are portable and can hold large amounts of data, making them a popular choice for both consumers and businesses. However, with the rise of digital downloads and streaming services, the use of optical media has declined in recent years.
