TDK 25GB Blu-ray Media Rated at 6x - Image courtesy PC Watch

TDK 100GB Media - Image courtesy PC Watch
TDK takes Blu-ray to 3 times the current media speed

With the bulk of Blu-ray writers launching at 2x write speeds, a higher speed media seems a little premature. However, TDK brought Blu-ray media rated at 6x to the 8th Annual Data Storage Expo in Japan and expects to launch media rated at 4x before the end of 2006.

The 6x media is a single layer 25GB Blu-ray disc which probably won't reap benefits until 6x drives come out. We are guessing we won't see 6x drives until at least later this year or early 2007 given the launch trends of previous optical standards.

TDK was also showing off 100GB Blu-ray media which we reported on back in April. The 100GB media uses a 4-layer process which has spacer layers between. TDK's latest trend graph shows a maximum speed of 4x for 100GB media.

TDK did again hint at 200GB media on that same trend graph which also shows a 6x write speed. The 200GB media is an 8-layer media on a single side. We probably won't see that density for another year or two so we’ll have to be satisfied with the current 25GB/50GB capacities.

recordable dl dvds are expencive because they use totally different specifications. they are like a strap-on extension to the original specs.

bluray was intended for high-capacity rewritable media from the ground up, so there won't be such significant price differences.

the launch prices for single and dual layer discs have already been announced, and duals are roughly just double the price. linear relation, as good as it gets i think.
we'll have to see if they drop in price equally fast though, and also at what prices the 4 and 8 layer discs might launch at.

and just for the record (and for those that asked) hd-dvd current specs top out at 2 layers, and there were plans to extend it to 3 but that'd take more than half the disc depth and i think they decided just making the discs double-sided, double layer is better.

HD triple layer was never canceled. It is a writable format only just like this.

Both HD triple layer (45GB) and BlueRay 4 layer (100GB) are for data storage not movies. ie R & RW not ROM.

So this 100GB disk WILL NOT play in your set top blueray player. The BlueRay video format top outs @ dual layer. Your set top player would not understand what to do with this disk.

So big question comes down to cost. If Blueray can deliver of $$ / GB and equal HD-DVD then I think it will win in data storage. Funny thing is one format could win in video/movie industry and another could win in data storage relm.

I personally think HD-DVD will be cheaper in terms of $$/GB than BlueRay and will get cheaper quicker. Capacity will ramp up quickly for HD-DVD since it can using DVD-R production equipment.

If in say 18months the costs are something like:
HD-DVD 15GB ($3)
HD-DVD 30GB ($7)

BlueRay 25GB ($10)
BlueRay 50GB ($20)
BlueRay 100GB ($50)
BlueRay 200GB ($120)

then I think HD-DVD will win. However if Blueray can deliver similar value in terms of $$/GB then it will likely win. BlueRay doesn't need to be cheaper because it has a higher capacity, but higher cap at much higher prices means it will be skipped. Just look at DVD-R and DVD-DL.

I think the whole point is moot, unless they come down lower than PATA, or SATA storage, people are going to start migrating to HDD storage instead. whats the point of buying a flimsy disk, when you can buy a USB 2.0 enclosure / HDD much cheaper ?

Interresting times indeed, but I personally think the time of removable storage is nearing an end, we'll see.

Imagine taking 25 hours movies in 1080P format on the road, would you take a HDD or 1 Blue-ray disc that only weight few ounce? ;)
