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.

BluRay Wins!!!

Well, looks like the format wars are over!!! BluRay holds far more than HDDVD ever will so they can just give up now. Finally I fell confident going out and spending my two month salary on a BD burner...

The issue is that CDs are still very prevalent and should be 100% compatible with the new players. It isn't like a major media change took place, as it is still optical disks at 12cm using refraction to indicate data. Unlike your analogy where the only similarities are shape, and the fact that they spin when they are played.

Not that I'd be playing CDs on a set-top movie player anyways... I mean, how many people use a DVD player for anything other than playing DVDs, even if they have the potential to play audio CDs, JPEG Photo CDs, or VCDs (well, the last one might appeal to some people, just not me)?

But I did see a demonstration of Blu-Ray at a local electronics store... Samsung had a display with their set-top Blu-Ray player and a 62" DLP television, which was nothing short of phenomenal (and made me wish that I had the $4200 needed to walk out of the store with both of them). There's still some minor niggles with the technology, but comparing it side-by-side with even HD content on digital cable wasn't even close (although I was impressed by the color vibrance on HD digital cable, this was only really taken full advantage of on commercials, something I could do without looking spiffy in HD). The first thing that came to mind was "I wonder what Advent Children will look like when it comes out on Blu-Ray".

You don't HAVE to move on to Blue-ray or HD-DVD....UNLESS you *want* to.

CD's are still very much mainstream and I see it being that way for a quite awhile (re: YEARS). Why? Well most home users don't really get into backing up things (sad to say, but its true)...and if they do the cheapo CD's are their first choice, even DVD's are cheap next to blueray media.

Finally, its not like CD's are ancient now -- when the majority of the PC using world STOPS using them...yes THEN you can say "Dude, time to move on don't you think?".

Personally I see nothing overly exciting about a Blueray burner, especially at current prices...If you do video work or write programs I can see value in it, CD's and tapes are still all the backup I need.

and which exactly recorder are you reffering to?
because there are plenty that can read and record cd, dvd and bd.
so just don't buy junk, instead of bitching about what it can't do.

It is one THEORETICAL advantage. As we learned with Beta/VHS the winner isn't always the one with the most options and nicest set up.

Personally, I can’t think of any PC user that would use a disk larger then 50GB. For the cost of 20-30 disks you could buy a tape backup system and a hard drive array with the same or greater capacity. That isn’t mentioning the cost of the burner or the fact that hard drives are a lot faster.

That is true but it would be awfully difficult to port around your hard drives and install them in a buddies in order to share that info with him...and how many people have a tape backup system anyways? I know it is an expensive technology right now but I think it also offers convenience not provided by other technologies...it is just too darn expensive for me...

external USB/Firewire/SATA HDDs... much easier to mess with than using a disc, although admittedly more bulky if you're only dealing with one disc vs. the enclosure (otherwise you might have to worry about a disc wallet).

The 8 layer stuff is interesting for all users in general, as it should be nice to have mere single discs (imagine the 4 disc LOTR expanded versions all on one disc, even with the movies in HD)

Granted, PC users are now finally starting to see DVD verions of games and the DL DVD @ ~8.5GB should be enough for the coming year or so, however it would be nice to know that the next format could last for quite some time instead of running out of steam before too long (which could be the case with HDDVD)

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?
