When talking about CDR writing, there has been talk which says
that more laser power is needed to write a cdrw than a cdr.
So if burning cdrw frequently, the laser lens(diode?) will consume
more than burning cdrs. I want to know if the same principle is
applied to DVD±R/RW? Is there large difference between the
writing power of DVD+R and +RW?
Thanks for your reply!
