Explain about the optical storage?

Optical storage is a storage technology that uses light to read and write data on a disc. This technology relies on the use of lasers to both read and write data on a reflective surface of the disc.

There are several types of optical storage media, including CDs (Compact Discs), DVDs (Digital Versatile Discs), and Blu-ray discs. These discs come in various storage capacities, with Blu-ray discs typically offering the largest capacity of up to 50GB.

To write data onto an optical disc, a laser is used to create pits and lands on the reflective surface of the disc, which represent binary information (0s and 1s). To read the data back, another laser is used to detect the reflections of the pits and lands on the disc.

Optical storage is popular for its high capacity, portability, durability, and compatibility with various devices such as computers, DVD players, and game consoles. However, optical storage technology is becoming less common with the rise of cloud storage and solid-state drives.
