Hopping on along to the TDK booth - a member of the Blu-ray
Disc supporters
club - we saw the company highlighting incredible leaps made
in BD capacities.
In the image below, the top-left disc is a single-sided 200GB
prototype. That's right, we're talking of a potential to store
over 40 DVDs' worth of
data on a single disc.
TDK has managed to reach this outlandish mark by
increasing the layer count to six and the capacity per layer to 33.3GB
from the usual 25GB associated with Blu-ray Disc media.
It's unclear whether current Blu-ray Disc drives will be able
to
support 200GB media but the prototype
needs to be passed by the Blu-ray Disc standards body before
certification
is approved. Whatever the case, at CES 2007, the supporters of Blu-ray
Disc look to have lots more to shout about than their HD DVD
counterparts.
You may be aware of the fact that Blu-ray Disc media has a
much
smaller coating layer than the 0.6mm coating on standard DVDs and HD
DVD media. The BD
discs shielding is just 0.1mm thick, so media makers have needed
to come up with methods to safeguard data. TDK's solution is its
Durabis 2 hard-coating technology.
The image above highlight the effectiveness of the
hard-coating technology against
the usual scratches and wear. Discs were abused with fine
wire
wool and a permanent marker. The disc on the left is a
standard DVD, the one on the right has
a Durabis 2 coating.
There's no noticeable damage to the TDK BD disc but this rough
treatement left the DVD
disc unplayable. Okay, that's not the most scientific of tests
but it does indicate that TDK's protective coating seems to work.
Want to know how multi-layer BD is constructed? The picture
above shows the process involved in engineering TDK's
four-layer 100GB prototype.
There's more to it than meets the eye.

Only time will tell what is going to happen, however LG? or someone else has been working on a dual player - player, to play both types of disc...

I know, DVD drives weren't this expensive when they first appeared were they?
Although, they didn't have a blue laser diode shortage to contend with as they were built on the same foundations as CD-ROM.
I remember a chap I knew payed £300 for an external cd writer back in the day.Quote
i think i bought a Plextor UltraPlex 40x for about £100 and a Pioneer DVD-ROM for the same.
EDIT: Also used a Pioneer DVR-101 that cost the company i worked for about £2k. It was used for DVD masters and needed the £20 "for authoring" disks that could handle Macrovision, Region Encoding and CSS (they didn't have the thin pre-recorded line that regular DVD-Rs have on them).Quote
BluRay for data and home recording, HD-DVD for commercial video.
I totally agree, this would solve a lot of problems :)Quote
