It occurs to me that when you write a DVD in your DVD writer that the DVD
that you place in the machine may have small particles of dust on some parts
of it. This dust would then block the laser from writing on these parts of
the DVD. Does the writer simply ignore this and move onto the next part of
the disc? What happens when the dust is cleaned off? Is the DVD simply read
as normal, ignoring these unwritten areas?
