I just had a confusion... Which is the top layer of an CD-R? Is it the data readable one, or the layer which you can scribble whatever you like on it?

And another question: for using the LabelFlash technology, do I need to buy special DVD-R discs or any type would work?

Thanks.

For Labelflash (which is similar but not the same as Lightscribe), burning images on the top side of a disc requires specialised media, but burning on bottom side (data side) of disc area which is not used by data is possible with any DVD R media.

As for the top layer of a CD-R, this is a very vague question as it depends how you're looking at it.

You can usually tell the top layer of a disc by the thin layer of print placed on the disc. The bottom layer is always just plastic so therefore if you ever scratch the bottom of a disc you have more a chance that it will work as opposed to the top layer being mishandled (o ohh!!). I can tel discs by the blink of an eye. You can personally bring me a disc so mirrored you would think it was top layers on both ends. I can still tell. Especially when you burn on one of them you can see the burnt rings by moving the bottom layer of the disc in light. Avoid too much exposure to light though because that is very bad for discs. So is heat, water, pens, pencils, and your own destructive habits!!!
