soo. i have been searching google but can't find anything.

why do dvd lasers have this line pattern? (this is a glass cover over the laser)
the laser eventually gets colimated into a dot small enoegh for the the engravings on the cd so why bother with the pattern?

No idea what part of the optical system this is I'm looking at so I can't really say. Can you provide more details?
