If your intent is to destructively erase data, then yes this is possible. But there are easier and faster ways. shredding, burning, melting, solvents.There simply has not been the demand to allow it, and some demand to prevent it. Optical drives are heading the way of the floppy, so like the optical serial mouse, this may never be commercial reality. Lightscribe was cool.

Remember, the code written is not really binary, there are limits to the run lengths of the mark and space ratios. You cannot "touch up" this code.

In the past I used dd myself to duplicate (to the sector) certain unfinalised DVD-R's burned by particular video cameras, when nothing else would work.
