My experience says otherwise. I have dealt with several burnt
CDs that were fine to start with but became partly or totally
unreadable after a while. I suspect it's not a question of
something "wearing out" but of the burnt layer deteriorating
over time. Note that many suppliers of blank CDs warn
specifically not to use certain pens when marking CDs. This
confirms that there is a chemical interaction between the surface
of a burnt CD and the environment.
On the other hand I find that hard disks are far more reliable.
