it has nothing to do with heat the more you use a laser or with every use it deteriorates, heat is taken care of by components in the dc which are responsible for thermal dissipation (the fan in the dc is designed to whisk this heat away from the unit), there is nothing the engineers can do about the laser it is a diode device that wears with time i built one in my fourth year in university as part of a communications device for my fourth year engineering project. If a laser is used significantly (number of hours is great) the device wears out and the power decreases therefore it will not be able to read data as well because of the conversion to digital strings of 1's and 0's , that's why you sometimes get hangups it is because there is an error generated from the pits and lands of the disc surface being read by the laser.
anyways
