Can dvd drive read blue light?

I can't. According to Sohu. Com, dvd uses a red reader with a wavelength of 650 nm, while Blu-ray disc uses a blue laser beam with a wavelength of 405 nm for reading and writing, so DVD drive cannot read blue light. Blu-ray has greatly improved the storage capacity of optical discs. For optical storage products, Blu-ray provides a leap-forward development opportunity.
