HD DVD whips out 51GB discs, surpasses Blu-ray (barely) in storage capacity | |

At the 2007 Consumer Electronics Show, Toshiba announced that it had developed a high-capacity HD DVD disc capable of storing 17GB on each of three disc layers, for a grand total of 51GB. It was good news for the HD DVD camp; before January, HD DVD storage capacities were 15GB and 30GB on single and dual-layer HD DVD discs, respectively. The DVD Forum has now signed off on Toshiba's technology, approving the new disc for public use. The move past 50GB is a big step for HD DVD. The overall storage capacity of the standard hasn't changed much since it was first spoken of as a Blu-ray rival in 2003 with its 15GB-per-layer storage. In 2005, there was talk about a 45GB three-layer HD DVD disc, but it never came to fruition. Back in 2003, Blu-ray was limited to 27GB per disc, but over time it has achieved its current storage capacities of 25GB and 50GB on single and dual-layer discs, respectively. | ||

| Does that mean to take advantage of these discs, everyone has to upgrade their players? If so, is it a hardware update, firmware update, or both? Does each reader have the capability to keep up with discs that introduce more layers as time goes on, or do we have to buy new players every time? If we have to get new players, will movie studios ever take advantage of larger storage for discs? Will increased size allow us to stream more data/second? As I recall, blu-ray has a higher data throughput and could theoretically display better video as more information can be sent for each frame. |

Or... is it even actually approved yet?
http://www.betanews.com/article/Toshiba_DVD_Forum_Hasnt_Yet_Approved_Final_51_GB_HD_DVD_After_All/1189716943 And even if it is, it's hardly going to be used mainstream for a while yet, especially with all the questions #1 poses that need to be answered first. So I don't think Blu-ray (or indeed HD DVD) users need to worry about a 3-layer HD DVD yet. |

Whatever it takes to kick BluRay off the map, I don't care...
