Noise When Putting In DvD Or Cd

[LJH68]

Is it normal for the mac to make such a loud noise when even just inserting a cd or dvd?
My lap top has always loaded like this from day one
So I thought it was normal until my friend said it sounds really odd
So my question is does everyones mac make this crunching noise when putting in a dvd or cd?
