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.

they used to say the same thing about DVD-/+R discs/recorders being too expensive when they came out, now they are bought in packs of 100, whats preventing BR from doing the same in the future? Seems everyone is focusing on release date pricing... its not called "Cutting Edge" technology for nothing, its because they cut into your wallet and bleed you dry for fresh releases. It will come down a lot, just give it 6 months...

Um because BR needs a new process, new equipment and lots ot capital to produce blank media. BR is sooo cutting edge that even Sony couldn't get the yields high enougb for dual layer disks and released its first 7 movies in single layer crap.

CD & DVD are basicly the same. Same size, same thickness, same size, same top layer etc. They are made on the same machines. Now the machines needed to be upgraded to handle the new wavelength, new dyes and tigher density but it was a rather minor. So what u saw happen was price of CDR stay basicly the same as price of DVD-R dropped as capacity shifted from CD-R to higher margined DVD-R.

Blueray needs new equipment so u wont see the same shift. DVD-R and DVD-R9 will get cheaper at a different rate than BR. If anything the current DVD media producers will try to cut costs even more to make the price between DVD-R & BR larger. They will do everything possible to keep the current $$$ machine alive for as long as possible.

This doesn't meant that BR will fail (or that it will succeed either) but dont assume the same thing that happened to DVD-R will happen to BR.

IF DVD-R9 (dual layer) 8x media from quality brands drops to less than $1 per disk in next year and BR drops to say $25 from $38 today for 50GB which is a better deal to you? 9GB for $1 or 50GB for $25? Even if you switch if 99% of people dont then BR will get cheaper but it will get cheaper slowly because it lacks a critical mass. Eventually the cost of DVD-R9 will be down to CD prices (pack of 100 16X disk for $20) then their will be an economic reason to ramp up BR disks as there simply isn't enough money in DVD-R9. Till then BR will get cheaper over time but dont expect the massive price drops of DVD-R which went from $10 disk to less than $1 in 3 years.

To make it more complicated their is a competitor HD-DVD. Now BR is more high tech but that could work against them. see HD-DVD is basicly an upgraded DVD (smaller wavelength, tighter pits) and can be produced from same equipment/materials. The dye is new but not much else is revolutionary more like evolutionary. So HD-DVD is cheaper than BR and if a large # of media companies decide to switch some (not all) of their production lines to HD-DVD it "could" get cheaper much quicker. So you could have a situation like:

BR 50GB $25
HD-DVD 30GB $8
DVD-R9 9GB $1

What would you do?
