to the professional optical storage market! Blu-ray is the proposed successor

to D$D and uses phase change recording technology to provide the storage

capacity to record a@ full-length #D"$ video! "he use of violet lasers and

high 2. optics dramatically increases data storage densities and

necessitates a new type of disk construction with a !1mm cover layer to

protect the data surface! .s with existing 9 technology, >D uses non

contact recording to provide roust and reliale performance!
