I was just wondering how durable the laser is its self... If I were to put something on my disk, a very small amount of water, or blood, would it cause harm to the laser? Also If I were to dissemble my blue ray player, exposed the laser, than put a small little drip of blood, or water on it, than put it back together and tried to watch a movie, would it harm the laser in ANY WAY? Do not ask why I said blood, I am just wondering because blood is thicker than water, so it makes sense.
