No, never. They have reached their physical maximum. Any faster and the bits would start flying off the edge. It is hard enough keeping them on now. Why do you think they are all horizontial instead of vertical? Gravity would pull off the bits if you spun them like that.
Honestly I don't ever see Dual Layer recording coming. The Tech alone to manufacture the discs would make it prohibitively expensive.
well although you may be right, i'm not really sure that is something you can say with technology, because things are always becoming possible and realistic that there weren't before
i see what you mean, but who though we would be burnign CD's or DVD's back when they FIRST came out...it wasn't realistic then to burn them
ok i didn't make a strong point but its a good one that i am not communicating well, do u get what i'm saying?
Don't get me wrong I'd love to see Dual Layers but it'll take a brave company to try. All DVD Drives read the layers fine but recording is a whole new beast. But someone will undoubtedly try...we might see it if it's good enough to get out the Lab.
Isn't 4x DVD ~5.4 MB/s which is about 36x for a CD-R which is pretty fast already, but since CR-R will go up to 52x (so they say) maybe there is some room.
Of course we will be able to burn Dual-Layer disks one day.
It's crazy to think anything else.
As far back as I can think, how many people that have predicted what we won't be able to do in the computer industry have been correct? Not many I think.
Every year I'm amazed what we can do. Back in the day when 1X CD-ROMs needed caddys because it was so difficult to hold the CD still and focus the lazer accurately.
Now we're burning DVD's with ease !!!
Sure the dual-layer blanks will be expensive when introduced, but so where 80min CD's.. let alone 99s.
What about DVD-recorders for your TV? In two years I've watched them go from 'not-possible' to around $10k to alot less than $3k.

Isn't the reason why CD-RW drives are limited to 52X is because the media cannot handled speeds much past that (i.e., the media rips apart in the drive). I would think data transfer rates is a technological limitation that will only improve over time. I think we will see a 16/24/36X drive (or faster) in the future.
Not for a while, not until the DVR-107 for the Pioneers anyway. Pioneer plans an incremental update from 105-->106 for the Summer, with actual speed increases coming in late Winter.
When I was shopping for my DVD drive I remember reading (in some DVD specific forum) a post by some guy who apparently was in the industry (maybe a Pioneer engineer) and a regular poster.
I remember him posting something about 8X burners this fall.
Sorry I'm so vague. When people asked about the incremental increase he stated something along the lines that the speed increases would develope very similarly to CD writing speeds. i.e. 4X . 8X> I think he even alluded to 6X being a possibility. Apparently the reason for this was all based on the laser limitations, he went into detail but i have since forgotten the reasons.
If 4x DVD is comparable to 36x CD-R, why is it they can actually only write CD's at 16x? \
Because a DVD burner writing at 4x isn't spinning as fast as a CD writer at 36x. Remember, DVDs have a much higher density per track than CDs, so the disc can write more data at a lower speed. I would imagine that either the particular motors they use are rated for the slower rpm (to be more precise and reliable) and/or because of the extra hardware involved (extra set of read/write lasers) they don't want to tax the hardware as much. I would imagine as this stuff advances you'll start seeing DVD burners which can burn CDs much faster.
I believe we will start to see some of the Blue Ray technology based recorders coming out this year. I believe the data versions will start at about 25 GB for single layer single sided, and eventually go to 100 GB dual layer dual sized. I don't suppose there should be any reason that the video version should not be able to do the same.

Super drives have always supported DVD-RW, you just can't use apple's disc burner software. Use Toast instead.

The Super Drives in the 12" and 17" Powerbooks do not support DVD-RW. It was disabled in the drive firmware for unknown reasons. Or so I am told.
Thanks
That's when I'll buy one.

VERY good question, for dubbing movies or 'time shifting' DVD2One meets all ur needs
truth is i do just time shift alot, i have a DVD-RW and just put my DVD on there before i return it to blockbuster till i get another one

It's always possible, just a matter of time.

By then, however, I'll probably be asking for 2x Blue laser discs. 30 Gigs per disc! Oh baby!

And is there a way to use it with Disc Burner in the Finder?
I'm off to the Genius Bar...
