\nThe correct answer is B) Laser light. Optical storage systems, such as CD, DVD, and Blu-ray drives, use laser beams to read and write data. The laser light interacts with the surface of the disc, reflecting differently off the ‘pits’ and ‘lands’ (or phase changes) that represent the stored binary data.
\n<\/section>\n
\nOptical storage technology relies on the use of focused light, specifically lasers, to interact with the storage medium surface for data retrieval and recording.
\n<\/section>\n
\nDifferent types of optical media use lasers of different wavelengths. For example, CD drives use red lasers, DVD drives use shorter-wavelength red lasers, and Blu-ray drives use blue-violet lasers, allowing for higher data density. Ultraviolet light, black light (which is also UV light), and general high-energy visible light are not the specific mediums used in standard optical data storage systems.
