At the CeBIT 2002 Matsushita Electric (Panasonic) demonstrates a burner with blue laser light that can write 50 Gbytes capacity on an optical disk.
The new disk is being talked about as one of the DVD predecessors. The optical medium is of the same size as a CD or DVD. It is rewritable and shall be able to store up to 50 Gbytes in two layers on one side. The first recording section consists of a half transparent layer with a film of 6 nm. It shall offer a transmissibility of 50 percent. |
Blue laser disc: The two-layer disc shall be able to store up to 50 Gbytes and probably could become the DVD predecessor in a few years.
According to Matsushita the maximum data transfer rate is 33 Mbits/s, that means it is thrice as high as that one of a conventional DVD-ROM. The medium shall be able to store more than four hours of digital movies in high resolution at a transfer rate of 25 Mbits/s.
The manufacturer plans to use the new technology for its recorders of the next generation but one for recording high resolution digital TV program (HDTV).
This is surely promising, but I hope when this comes to the general public they have a good standard for it
