Well, this is the newest change in how we view video and its in HD. So the question is, what is Blu-Ray and how does it work? The answer is quite simple- Blu-ray Disc is a high density optical disc format that stores digital info and HD video. Basically, its able to store more information than the typical dvd because it uses a blue violet laser, which has a shorter wavelength, to read and write the discs.
