How Does Nanotechnology Enhance Blu-ray?

Nanotechnology plays a critical role in enhancing Blu-ray technology. By leveraging nanoscale precision, engineers can create more accurate and efficient optical components. The blue-violet laser used in Blu-ray operates at a wavelength of approximately 405 nanometers, which is shorter than the 650-nanometer wavelength of the red laser used in DVDs. This shorter wavelength allows for smaller pits and grooves on the disc, resulting in higher data density and greater storage capacity.
