According to Japanese website Nikkei.net, Sanyo has developed a blue laser diode which will pave the way for more acceptable writing speeds for both the HD DVD and Blu-ray Disc formats. The diode, which is fully compatible with both formats, will speed up data access on the discs and will be able to provide burn speeds of "up to 6x on dual-layer discs".
This would be a great improvement over the current available burners for both formats. While it is possible, there are no hints to whether this diode will be used anytime soon to produce a hybrid HD DVD / Blu-ray Disc burner. A 6x burner for dual layer discs is a big step in the right direction either way.
