Will OC shorten my drive's life?

I’m new in CD writter OC, i’ve successfully flash my TDK Cyclone 48x to LiteOn 52x, just wan to know will it shorten my writter’s life? i know that the chipset for both TDK 48x and LiteOn 52x r the sam, how about other parts? any physical difference between them? (disgarding the look)

If the drive can be overclocked successfully, the parts would have to be functionally the same.

Probably not. But what’s the point? 48x to 52x is so little difference you probably wouldn’t even notice. Not to mention the expense of the higher rated media. I wouldn’t bother, but then again I think ocing 40 to 48 is a waste as well.
