A stupid question, but would still like to discuss
 

Hi.....I know, whatever i am gonna ask u is probably my stupidity, but anyways....

See, We all know that a CD-ROM drive is not capable of reading DVD's. However, since linux treats everything as a file, is there a chance that it can emulate a DVD-ROM drive without there being an actual hardware device for the same?

Whenever i insert a DVD in the CD ROM drive, at first it tries to read it, and then later ejects it. Is it possible that linux gets a CD-ROM drive to read DVDs???? or any package that makes this possible???

I know I may be stupid...but i'd like answer to this one..

thanks..

No. Not only is the data density on a DVD is much higher than on a CD, but there are multiple data surfaces on a DVD while there is only one data surface on a CD. Thus, there is no way to tweak a CD-RW to cope with a DVD.

Specifically: "The track pitch on a 3.95 GB DVD-R disc is 0.8 microns, one-half the track pitch of a CD-R. The track pitch on a 4.7 GB disc is 0.74 microns. Hardware changes in the recorders allow the creation of data marks approximately one-half the size of those made on CD-R media (0.40 microns versus 0.834 microns). The recording laser's wavelength and focusing lens' numerical aperture were changed. Because of this, a CD-R/CD-RW drive cannot be used to write DVD-R media. Additionally, DVD-R substrates are injection molded to one-half the thickness of a CD-R. Two DVD-R substrates are bonded together creating multiple recording surfaces."

The above comments are in relation to writing a DVD, but they apply to reading one too. Unfortunately bro you're going to need to buy a DVD player. If anyone has info to the contrary, please post it. -- J.W.
