I am making copy of a VCD disc by using Adeptec.

Problem is when I use CD-R disc, everything is fine. But when I tried to use CD-RW disc by doing the same as CD-R disc, my VCD player nor MediaPlayer on my PC couldn't read it, keep telling me "there is no disc".

Anyone know what's wrong?!

Thanks in advance.

This is just an educated guess answer. The fact that my burner can identify a blank CD-RW disc from a blank CD-R disc when I load one in (although the two discs looking identical), the CD-RW disc and the CD- R disc must be not identical in every way. Something on the disc track must distinguish them apart.

CD-RW is a very new technology, therefore only very recently made multi-read CD-ROM drives, DVD-ROM drives, DVD players and CD-RW burners are made to recognise it.

I find that very recently made VCD/CD(only) players, probably for cost cutting reasons, must be employing obsolete CD-ROM drives or are not bothered with providing extra features to read CD-RW discs. I also find that CD-R(only) burners do not recognise CD-RW discs.

The difference is the media and the way it is used. CD-R is designed to be burned one time and the color of the recording surface changes to reflect that. The CD-RW also modifies the color of the recording surface but can be written to and re-written to. CD-RW, however, loses space. You burn 50 mbs and the CD-RW reflects that, delete it and it will not show up in Explorer but those 50mbs are not accesible anymore. The machine just marks the area where the last write was and goes from there.
