DVD---CD question:

[acidrain]

Is it true that DVD's will read CDR/CDRW's.......??

Thx

All modern DVD ROM drives will read pretty much all CD media including CD-R/CD-RW.

ALthough from what I hear some of the first and second generation (all but completely gone now) had trouble with some CD-R's.

for more info go to The DVD FAQ (http://www.cd-info.com/CDIC/Technology/CD-R/FAQ.html) to find out pretty much anything you might want to about the CD & DVD format.

Yes, they read. And with much faster speed. I saw DVD reading CD's at 100x!!! (not tested by me).

[vibe666]

i find that hard to believe (no offense intended Kurylo). DVD ROM drive speeds are rated differently than CD ROM speeds, but when you buy a DVD ROM it will tell you the rated CDROM reading speed as well.

i have a Pioneer 16x DVD ROM and i am pretty sure the box said it would read 's at 40x as well.

i think you may have mis read something.

aside from anything else my 12x10x32 CD Writer passed all the Roxio CDROM tests that come with WinOnCD significantly faster faster than the DVD did.

anyone else think any different?;)

[Kurylo]

You're right. CD-RWs read at a higher speeds and more stable, 'cause they have more exact mechanisms and more developed error corrections.
As for 100x, I've read about it in a journal (just don't remember in which of them). I remember I wondered: 100x ??? False! Once I had an 48x CD-ROM. After it had cracked and killed severe CD's. I've changed it to 40x TEAC, and that effect disappeared. So, what will be with 100x ??? Maybe, it was just a some type of propaganda?

[Kurylo]

BTW, to calculate: 1x DVD = 8x CD (DVD 1x = 1200KBpS, CD 1x = 150KBpS). So, your 16x DVD (with a linear dependancy) should have 8*16x=128x CD reading speed... Another dilemma... Where do another 88x vanished?

I'm sure it's propaganda. 1x DVD is 1385kb/s, 1x cdrom is 150kb/s. It must have been a 12x DVD drive with a transfer rate of about 16mb/s which is more than 100x for cdrom. This doesn't mean that the drive can read cdroms at that speed. The fastest cdromdrive is, as far as I know, the Kenwood TrueX 72X drive. This thing is awesome: 72X max CDROM, over 40X digital audio extraction! But the price is even higher...:(
