400GB Optical Discs

Pioneer has developed a 16-layer read-only optical disc (you cannot burn data on it) which claims to store 400GB of data. The per-layer capacity is 25GB, the same as that of a Blu-ray Disc. If this was announced few months back then people will think its totally un-practical to have so much space and data on a single disk but today I see such disk will be of great use for providing high definition content. More people are buying high definition LCD TV’s and these people will experience a great video quality as there will be no need to compress videos and even longer videos will fit on single disk. Still this disk will not be for a mass market as not everyone is equipped well to play such high definition movie at home.
