Can DVDs be used with CD writers? My thinking is no, but I have not been up on new developments in the burning world.

I used to know this in detail but the mists of time are particularly dense tonight. :)

The laser in a CD drive has a particular angle of attack.

The laser(s) in a DVD drive have multiple laser angles. A legacy one for CDs and a completely different 'angle' for DVDs.

I think the colour of the light beam is also another variance.

It's all to do with the depth of the dye-emulsion on the writable surface of the discs.

Commercially manufactured CD/DVD discs have their digital 'pits' created in a completely different manner, therefore a CD writer can read a manufactured DVD, but not a computer-generated one.

Hmmm...if I have some blank DVDRs, can I burn with them on a CD writer?

Thanks

your cdrw will not be able to use the format, or determine what media is available. therefore you cannot burn a dvd with a cdrw. You will need a DVD +/- RW drive
