personally i wouldnt touch that media, as crap media burns your laser out.
Congrats!!!!! Thats the most retarded thing I read today (its still early).
A laser is not going to burn up from media. There is just no way. I don't think you understand what its doing. Its JUST a flashlight (more like a flashlight with feedback, but thats how YOU can think of it, since 'laser' is too complicated apparently)
The only argument you could even attempt to make is "the disc media sucks so it has to read it more, thus it heats up more" but thats not the case. These drives are designed for how ever many hours of continuous use. The diode is driven solely by pwm, a dac from the micro handles this and its never going to 'overdrive' itself. The harmful result of reading a bad disc for 10min is identical to the ware and tear of 10min of good disc use. That goes for the diode, motor, and any adc / dac / drivers / gates / fets / resistors / caps / etc.
Its like telling someone that your flashlight will die faster if you shine it at ugly people.
I'm an EE so if you want to get schooled on the subject you can PM me. In any case PLEASE stop posting such garbage. It hurts my head.
