How fast will DVD burners get?

[BillGates]

I was impressed to see that CD burners got to 52x but suspect that they're approaching the limit.... The fastest DVD burner I've seen is 4x. I know that these two speeds are not comparable, but how fast do you forsee DVD buring speeds getting? What will be the bottle neck? I'm suspecting it will be the transfer rate between the hard drive and burner but may be incorrect.... Any info on this?

Actually I think the limit is the amount of heat that can be applied to the disc without burning the thing to where it's unusuable.

In one of the many DVD + vs - threads I think I saw 8x as the highest safe speed before you start getting shattering like with 52x CDs. Since only 2x media is really affordable now it will be another year or two before 8x will be of any benefit to most people.

Will we be planning on seeing the Blu Ray DVD's by then too?

I don't think we will until we really need it because there are many homes still without even a DVD player so some people would be jumping a generation of technology going from VCR's to Blue Rays.

Probably 8X. Read some info here

But isn't a 1x DVD ~9x for CDRom? So 8x actually makes sense then....

So a 4x Burner is also a decent speed if you think about it assuming what I THINK about at 1:9 ratio is true

If you do the calculations, 50X on a cdrom has about the same angular velocity as 16x on a dvd. But I've read that DVD's are mechanically stronger than CDs so they may be able to reach ~20-24x. However, since DVDs have concentric data tracks unlike CDs, it would be an easy matter to make a multibeam DVD recorder/player.

 

[yeedog]

just a random questiong, but how long does it take to burn a DVD right now at 4X, using 4X media for +R and -R? Sometime more specific then less then 20 minutes would be great.

Plus is it safe to assume that at 8X the time would be half of the 4X?

thanks!

Also, keep in mind that DVD's can spin faster than CD's because they are mad eout of stronger material so even if there is a 1:9 ratio for speed, you can't compare to how fast CD's can spin at max unless they have the same surface, or a surface you can compare.

Note that 52X on a CD is not 52X. It's about 40X average. (It's 52X only on the outer track, and the beginning write speed is only about 24X.) 4X DVD is.... well... 4X DVD, which is about 37X in CD-ROM terms.

So in other words, a DVD recorder today already writes almost as fast as a 52X CD-ROM drive, and faster than a 52X CD-ROM if you're only writing short portions of data.

My uneducated guess is that 8X DVD burning will be the max before we switch to some other technology. That'd be something like a "real" 74X CD-ROM drive, or else close to a 100X CD-ROM drive if we use today's misleading CD-ROM numbers.

I though the increase in the amount of data being read from a DVD when compared to a CD was also due in part from the decrease of the size of pits? So that a DVD could spin at the same speed as a CD, and the laser would read more information in the given area or speed of the disc? Am I mistaken?
