It has greater storage capacity than DVDs, uses a blue laser rather than red, and is compatible with previous formats. The document discusses Blu-ray disc types, how they work in single or double layers, their specifications compared to CDs and DVDs, applications for high definition video and data storage, and concludes Blu-ray will likely replace DVDs for optical storage.
