well I never noticed this...
from the description of each I dont see any difference...
is the difference in locating laser beam?...
well, if there's a difference please let me know. they're both, I think, are the same. or one is better for storing data and the other is better to play movies? I doubt that but Im still not sure. so please let me know whats the difference and which type is better for what purpose if they differ somehow
thanks
