burning - Is there a lifespan for a dvd rom drive?

Specifically a liteon dvd multi recorder. Which can burn and read dvd's.
Is there a specific number of burns which you can use? And after that, the burner will no longer work?
Do you know of any useful tips on how to have a longer dvd rom lifespan?If it has really a lifespan.

Answer

Lifespan only depends on the environment. If there is much dust/smoke/dirt/etc it may break sooner.

Also if the Drive isnt used regularly (reading CD or DVD is enough), it will break sooner.
