Before racing out and buying a new burner there is a possibilty that after 18 months the laser lens has a fine coating of dust on it and just needs cleaning, this can be done in two ways but the safest being is to buy the lens cleaner disc from Tandy or Radio Shack depenging on where you come from. You put the cleaner disc in the same as a normal cd and hit play and it cleans dust off the lens. Try that, it may save you some dollars.
